VizMe : 소스코드를 분석하기 위한 알고리즘 자동 시각화 시스템 = VizMe : Automatic Algorithm Visualization System for Source Codes Analysis

다국어 초록 (Multilingual Abstract)

Complex software development is the cause of the increasing man-month cost. And maintenance of complex software is need to large man-month cost. Modi-cation of the source code is one way of software maintenance. If the programmer modify the code written by another programmer, understanding of the source code is required. In general, owchart representation is an easy way to understand the source code. On the other hand, developers using a the automatic owchart generator to draw a owchart quickly and easily. However, the output of the automatic owchart generator is dicult to understand the source code. This paper proposes VizMe, an automatic visualizer of source codes for the understanding of the algorithm. VizMe is an automatic generator of owchart, PAD and pseudo-code. VizMe supports to source code written in C, Java and Scheme Language. The Programmer want to put information in the owchart, it is need to add the meta tags in the source code. In this paper, comparison of owchart and PAD using density, cyclomatic complexity and graph entropy. The measurements of density (owchart: 0.027, PAD: 0.024) and cyclomatic complexity (owchart: 8.6, PAD: 1) shows that PAD is easier to understand than the owchart. The comparison of graph entropy shows that PAD (0.469) is higher than that of the owchart (0.356). Because PAD is higher degree than owchart when represent a branch statement. Using VizMe in all phases of software development, that is thought to contribute to improving software quality and reducing man-month.
