Abstract—There are two main approaches to solve classified
problems: using the method of comparing strings and abstract
syntax tree (AST). In terms of the method of comparing strings,
it has many obstacles because it is not recognized by a wide
range of changes such as additions, deletions or editions about
information on the number of exams or creating called functions
without returning any values. This research is utilized by the
AST algorithm in order to match and compare students’ source
codes to AST tree.
Index Terms—Duplication code (DC), clone code, abstract
syntax tree (AST), string matching, semantics, fuzzy means.
