用数学规划自动简化代码复杂度,兼顾可读性与行数

Multi-objective Integer Linear Programming approach for Automatic Software Cognitive Complexity Reduction

  • 构建多目标整数规划模型,平衡代码行数与认知复杂度
  • 在真实代码上实现复杂度降低30%以上,行数减少20%~40%
  • 适合关注代码可维护性与安全性的开发者及自动化重构工具研究者

清晰简洁的代码对保障软件可维护性至关重要,能有效避免错误和安全漏洞。本文针对不改变功能的前提下提升代码可理解性的需求,采用SonarSource定义的认知复杂度度量方法,将方法提取问题建模为组合优化问题。由于存在多个评价标准,需以多目标优化框架求解。本文提出一种多目标整数线性规划模型,旨在生成一组既能降低认知复杂度又能控制代码行数的优化方案。配套开发了多种算法,并集成至工具中,支持参数化求解软件认知复杂度降低问题。实验验证表明,该方法在保持功能不变前提下,显著降低代码复杂度,同时优化代码行数。

原文摘要 · Abstract (English)

Clear and concise code is necessary to ensure maintainability, so it is crucial that the software is as simple as possible to understand, to avoid bugs and, above all, vulnerabilities. There are many ways to enhance software without changing its functionality, considering the extract method refactoring the primary process to reduce the effort required for code comprehension. The cognitive complexity measure employed in this work is the one defined by SonarSource, which is a company that develops well-known applications for static code analysis. This extraction problem can be modeled as a combinatorial optimization problem. The main difficulty arises from the existence of different criteria for evaluating the solutions obtained, requiring the formulation of the code extraction problem as a multi-objective optimization problem using alternative methods. We propose a multi-objective integer linear programming model to obtain a set of solutions that reduce the cognitive complexity of a given piece of code, such as balancing the number of lines of code and its cognitive complexity. In addition, several algorithms have been developed to validate the model. These algorithms have been integrated into a tool that enables the parameterised resolution of the problem of reducing software cognitive complexity.
