The real coded Genetic Algorithm (LX-PM) that uses Laplace Crossover and Power mutation became popular to find optimal solution. In recent past, the LX-PM is being hybridized with a local search called Quadratic Approximation (QA) to improve the solution quality. However, there are some instances to improve it further, just by checking the frequency of hybridization. In this paper, a self adaptive strategy of hybridization is incorporated in the cycle of LX-PM. The improved efficiency and efficacy of the adaptive hybridization of QA over the simple hybridization of QA with LX-PM, is being realized through a set of 22 unconstrained benchmark problems. Comparative result is being analyzed through the numerical results, in terms of five different aspects.
