A Study on Performance of the (1+1)-Evolutionary Algorithm

چکیده
The rst contribution of this paper is a theoretical comparison of the (1+1)-EA evolutionary algorithm to other evolutionary algorithms in the case of so-called monotone reproduction operator, which indicates that the (1+1)-EA is an optimal search technique in this setting. After that we study the expected optimization time for the (1+1)-EA and show two set covering problem families where it is superior to certain general-purpose exact algorithms. Finally some pessimistic estimates of mutation operators in terms of upper bounds on evolvability are suggested for the NP-hard optimization problems.

متن کاملAn Evolutionary Multi-objective Discretization based on Normalized Cut
Learning models and related results depend on the quality of the input data. If raw data is not properly cleaned and structured, the results are tending to be incorrect. Therefore, discretization as one of the preprocessing techniques plays an important role in learning processes. The most important challenge in the discretization process is to reduce the number of features’ values. This operat...
