Abstract: E-commerce has transformed the way firms to develop their pricing strategies，producing shift away from fixed pricing to dynamic pricing.This paper uses two different evolutionary computation algorithms，Genetic Algorithm（GA） and Population Based Incremental Learning Algorithm（PBIL） for solving two different dynamic pricing models and compares two algorithms.Promising results and analysis are obtained from PBIL confirming its suitability for resource management in the proposed model and applicability of population based optimization techniques for dynamic pricing.
