Methods and system are disclosed that support optimization for markdown in retail domain to generate an optimized price for a product. The markdown optimization is mapped to a genetic algorithm. In one aspect, an initial population of candidate solutions initializes the execution of the genetic algorithm. Based on a fitness function associated with an objective, the genetic algorithm iteratively executes on the initial population of candidate solutions to compute a fitness score corresponding to each candidate solution. In another aspect, based on the fitness score, the candidate solutions are selected to breed or generate candidate solutions for next-generation. The genetic algorithm terminates when a termination condition is met and may generate a set of particularly desirable result set. In yet another aspect, particularly desirable result set is validated by applying constraints and the validated particularly desirable result set represents most desirable result set.
