- An Experimental Study of an Information-Based Complexity Metric.
- Creator
- Danaher, Mary Schindlbeck, Florida Atlantic University, Coulter, Neal S., Harold, Frederick G., Munson, John C.
- Abstract/Description

Through a small contained environment, this study evaluates an information-based complexity metric theory and its relationship to the effort expended in constructing a program. The metric, which calculates the amount of information present in a program specification, determines the specification's complexity measure. The observed measures of programmer effort were the numbers of keystrokes, insertions, deletions, and runs needed to complete the program specification. It was theorized that a...
Show moreThrough a small contained environment, this study evaluates an information-based complexity metric theory and its relationship to the effort expended in constructing a program. The metric, which calculates the amount of information present in a program specification, determines the specification's complexity measure. The observed measures of programmer effort were the numbers of keystrokes, insertions, deletions, and runs needed to complete the program specification. It was theorized that a program with a higher complexity value than that of another program will require more programmer resources to complete. A significant relationship between the metric and the number of keystrokes was found.

Genetic Programming is an evolutionary technique for searching through the space of S-expressions for programs that represent optimal or acceptable solutions to a given problem. Genetic Programming often has difficulty in finding the appropriate numeric constants to use in leaf nodes of the S-expressions.

Genetic Programming often has difficulty in finding the appropriate numeric constants to use in leaf nodes of the S-expressions. This thesis describes the use of local search algorithms to search for numeric constants that will improve the S-expressions found by Genetic Programming. Three methods, Multi-Dimensional Hill Climbing, Vector Hill Climbing, and Numeric Mutation are combined with Genetic Programming to create hybrid systems. The performance of these hybrid systems is analyzed and future directions for improving Genetic Programming with the use of hybrid systems are discussed.

Show moreThe purpose of this study was to determine if success in writing computer programs is related to level of cognitive development, verbal ability, math reasoning, and grade point average. This study presents a model that predicts computer programming ability. Twenty-three subjects were drawn from students enrolled in BASIC programming classes at Broward Community College. Each subject was given the School and College Ability Test (SCAT II) test to assess math and verbal levels and the Inventory of Piaget's Developmental Tasks (IPDT) to assess level of cognitive development. Grade point averages were obtained from the registrar. The instructor's final examination, which consisted of generating BASIC programs, was used as a measure of programming ability. Each student was given 45 hours of instruction in BASIC by the instructor and had access to laboratory facilities equipped with IBM Personal Computers. Pearson r correlations were performed using each predictor (grade point average, verbal ability, math reasoning, and level of cognitive development) as independent variables and computer programming ability as the dependent variable. The correlations were all significant. To determine how well all four factors together predict programming ability, multiple regression analysis was performed using all of the predictors as independent variables and computer programming ability as the dependent variable. This study supports prior research showing that grade point average, math reasoning and verbal ability were each significant predictors of success in computer programming. Results showed that level of cognitive development is linearly predictive of success in computer programming. Results of the regression showed that level of cognitive development, when combined with verbal reasoning, is linearly predictive of programming ability.

Show moreAccompanying the potential increase in power offered by parallel computers is an increase in the complexity of program design, implementation, testing and maintenance. It is important to understand the logical complexity of parallel programs in order to support the development of concurrent software. Measures are needed to quantify the components of parallel software complexity and to establish a basis for comparison and analysis of parallel algorithms at various stages of development and implementation. A set of primitive complexity measures is proposed that collectively describe the total complexity of parallel programs. The total complexity is separated into four dimensions or components: requirements, sequential, parallel and communication. Each proposed primitive measure is classified under one of these four areas. Two additional possible dimensions, fault-tolerance and real-time, are discussed. The total complexity measure is expressed as a vector of dimensions; each component is defined as a vector of primitive metrics. The method of quantifying each primitive metric is explained in detail. Those primitive metrics that contribute to the parallel and communications complexity are exercised against ten published summation algorithms and programs, illustrating that architecture has a significant effect on the complexity of parallel programs--even if the same programming language is used. The memory organization and the processor interconnection scheme had no effect on the parallel component, but did affect the communication component. Programming style and language did not have a noticeable effect on either component. The proposed metrics are quantifiable, consistent, and useful in comparing parallel algorithms. Unlike existing parallel metrics, they are general and applicable to different languages, architectures, algorithms, paradigms, programming styles and stages of software development.

G-LOG was designed to be a transportable, easily extensible non-procedural language which provides easy access to routines written in other programming languages. A primary use of G-LOG will be for the construction of a non-procedural executive for an expert system which calls existing routines to execute procedural functions. This versatility should enable industry investments in complex programs to be updated into a customized expert system. The history and philosophy of PROLOG is sketched first, then the syntax required by G-LOG is presented. The implementation of G-LOG is discussed in detail. Novel aspects of G-LOG include semi-compilation of variables and user-written system primitives. Guidelines for the application programmer are given.

The proposed API is organized in such a way that it can easily be integrated with the existing suite of APIs defined in the Java 2 Micro Edition (J2ME)---the Java edition that specifically targets mobile devices. The proposed API provides J2ME programmers with components that simplify multiplayer mobile game development process. The main idea of the API is to encapsulate low-level technical details associated with establishing and maintaining communication links between mobile devices. A programmer who uses the API is only concerned with the high-level multiplayer aspects of programming such as managing game players and sessions. The actual implementation of the API on each target device is responsible for utilizing the supported underlying network protocols such as the Bluetooth, HTTP and IEEE 802.11b.

Show moreThree major problems make Genetic Programming unfeasible or impractical for real world problems. The first is the excessive time complexity.In nature the evolutionary process can take millions of years, a time frame that is clearly not acceptable for the solution of problems on a computer. In order to apply Genetic Programming to real world problems, it is essential that its efficiency be improved. The second is called overfitting (where results are inaccurate outside the training data). In a paper[36] for the Federal Reserve Bank, authors Neely and Weller state “a perennial problem with using flexible, powerful search procedures like Genetic Programming is overfitting, the finding of spurious patterns in the data. Given the well-documented tendency for the genetic program to overfit the data it is necessary to design procedures to mitigate this.” The third is the difficulty of determining optimal control parameters for the Genetic Programming process. Control parameters control the evolutionary process. They include settings such as, the size of the population and the number of generations to be run. In his book[45], Banzhaf describes this problem, “The bad news is that Genetic Programming is a young field and the effect of using various combinations of parameters is just beginning to be explored.” We address these problems by implementing and testing a number of novel techniques and improvements to the Genetic Programming process. We conduct experiments using data sets of various degrees of difficulty to demonstrate success with a high degree of statistical confidence.

The software has been written f o r the 80286 based machine in assembly and compiled basic. Since this research was aimed at defining techniques that could work for speech recognition, real time recognition was not a goal. Three techniques were tested for speech recognition. The first method tried to match entire words, using the fast Fourier transform, the fast Walsh transform, the average magnitude function, and the zero crossing rate. The second method used the short-time fast Fourier transform to recognize the phonemes, then the words. The third method used a digital filter generated from I in ear predictive coding coefficients and the zero crossing rate to recognize the phonemes and words. A recognition rate of 98 percent was achieved for a single user for the words zero through nine.

The programming languages currently being taught feature a systematic breaking down of a problem into manageable parts instead of stressing an overview of the entire problem and all its possible implications in its environment. PROLOG, a computer language which allows programming in logic, is a descriptive language. The goals of including PROLOG in the repertoire of a student's skills are to build a familiarity with a logical system to approach open-ended questions and multistep problems and thereby achieve an enhancement of reasoning abilities. The text and exercises developed were used to teach reasoning in PROLOG to three groups of university level students.

Show moreWe survey and compare the different major mechanisms for embedding the relational database language SQL in object-oriented programming languages such as Java and C#, with regard to how much impedance mismatch these embeddings suffer. Here impedance mismatch refers to clarity and performance difficulties that arise because of the nature of the embedding. Because of the central position in the information technology industry of object-oriented programs that access SQL-based relational database systems, reducing impedance mismatch is generally recognized in that industry as an important practical problem. We argue for the suitability of SQL as a database language, and hence for the desirability of keeping SQL as the view provided by a SQL embedding. We make the case that SQLJ, a SQL embedding for Java in which it appears that Java directly supports SQL commands, is the kind of SQL embedding that suffers the least impedance mismatch, when compared with call-level interfaces and object-relational mappings. We propose extensions to SQLJ that would reduce its impedance mismatch even further.

Show moreEnhanced system design productivity is key to satisfying time-to-market demands. One will have to exploit design reuse methodology to meet project schedule requirements. Integration of components often fails due to various concurrency violations. Concurrency issues arise when components executing in parallel share resources and interact with each other. Such a system may have intermittent, yet catastrophic failures, if these concurrency issues are not addressed properly. In this thesis, we propose a methodology for developing concurrency compliant components from a requirement document. We have applied this methodology for developing process management and memory management aspects of a Real Time Operating System (RTOS). In this methodology, we start from a "customer' s" requirement document that is then mapped to activity diagram, swimlane diagram, class diagrams, and use case diagrams. To evolve a concurrency compliant design, we use the Message Sequence Chart plug-in for the Labeled Transition State Analyzer (LTSA). This plug-in lets us use Message Sequence Charts rather than coding in Finite State Processes (FSP). Later, we use MLDesigner to simulate our R TOS sub-system and demonstrate proper behavior of this sub-system.

Method and Sources: Two levels of students, secondary and post secondary, were divided into equal-sized control and experimental groups. The control groups followed the traditional method; the experimental groups were instructed by specially prepared audio instructional tapes with a correlated program folder of examples, exercises, and evaluations . All groups were given an achievement test evaluating speed and accuracy in addition and efficiency in applicable business problems. Findings: Experimental groups achieved higher mean scores. At the .05 level of significance, there was a significant difference in achievement in favor of the experimental group at the high school level. Students liked the audio method. There was indication that both student and teacher productivity increased.
