The recombination (or crossover) operation is a method of sharing information among chromosomes in genetic algorithm(GA). The neighborhood- based crossover operators used in real-coded genetic algorithm (RCGA) are based on some probability distribution. In this paper, we propose MPX (multi- parent crossover with polynomial distribution) and MLX (multi-parent crossover with lognormal distribution) operators. These operators are gene- based parent centric crossover operator. The performance of these operators is investigated on commonly used unimodal and multi-modal functions. It is observed that these operators are capable to solve problems very efficiently. The performance of these operators is compared with the performance of other operators. These operators are performing better than other operators.
