An algorithm based on the human evolutionary model is proposed for solving nonlinear bilevel programing problems. In view of the hierarchical structure of this problem. the algorithm is designed through feeding back the optimal solution of the lower-level problem to the upper-level. Based on the quality of individuals at each iteration. https://www.roneverhart.com/Traditional-Karate-Do-Okinawa-Goju-Ryu-Book-1-The-Fundamental-Techniques-by-Morio-Higaonna-Preowned/
