We study both genotypic and phenotypic convergence in GP floating point continuous domain symbolic regression over thousands of generations. Subtree fitness variation across the population is measured shown many cases to fall. In an expanding region about root node, genetic opcodes function evaluation values are identical or nearly identical. Bottom up (leaf root) analysis shows syntactic seman...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

Background and Objective: In recent decades, epidemiology has significantly been considered in hygienic studies and disease control, and has made a way into all the programs and hygiene policies. By examining the convergence of harmful lineage genetic patterns, the common infectious resources among the patients can be inferred. The purpose of this study was to compare the Mycobacterium Tubercul...

One of the major purposes of optimization in civil engineering is to perform a suitable design for the structure. This goal has to fulfill technical criteria and contain the minimum economical costs. Building frames are of the most customary civil engineering structures. Therefore, optimization of these types of structures could be of a great concern from the economical viewpoints. One of the c...
