Search based Software Engineering of Software Metrics, Code Smells and Refactoring Techniques Using Optimization Algorithms

Abstract

Software refactoring is a technique for reorganising and improving the efficiency of existing software code. By refining the non-functional aspects of software, numerous refactoring methods are currently being employed to build more intelligible and less composite codes. By applying multiple systems to the source code, refactoring can improve code maintainability even further, preserving the behaviour of the code. Refactoring allows for the eradication of bugs and the expansion of the program's capabilities. This paper provides a comprehensive assessment of source code with foul odours, the influence on software quality of using certain refactoring methodologies to eradicate the foul smell. Between 2008 and 2010, a total of 76 studies from 42 journals, 20 conferences, and 14 additional sources in the year 2008 and 2022 were available. This study was graded on the number of unpleasant odours identified, refactoring strategies applied, and their impact on software metrics. The foul smells of "method of long," "envious feature “and” class of data" were discovered or corrected in the majority of inquiries. The odour of "envious feature" was detected in 39.66 per cent of nominated investigations. The majority of studies looked at the effects of restructuring on software intricacy and coupling measures. Surprisingly, instead of patented software, the majority of the investigations employed massive opensource datasets released in Java. Finally, this research makes suggestions for further into the refactoring research code.
