  abstract =     "The present work is a heuristic and experimental study
                 in the evolutionary computation domain, and starts with
                 an introduction to the artificial evolution with a
                 synthesis of the principal approaches.

                 The first part is a heuristic study devoted to
                 constraint handling in evolutionary computation. It
                 presents an extensive review of previous constraint
                 handling methods in the literature and their
                 limitations. Two solutions are then proposed. The first
                 idea is to improve genetic operator exploration
                 capacity for constrained optimisation problems. The
                 logarithmic mutation operator is conceived to explore
                 both locally and globally the search space.

                 The second solution introduces the original Adaptive
                 Segregational Constraint Handling Evolutionary
                 Algorithm (ASCHEA), the main idea of which is to
                 maintain population diversity. In order to achieve this
                 goal, three main ingredients are used: An original
                 adaptive penalty method, a constraint-driven
                 recombination, and a segregation selection that
                 distinguishes between feasible and infeasible
                 individuals to enhance the chances of survival of the
                 feasible ones. Moreover, a niching method with an
                 adaptive radius is added to ASCHEA in order to handle
                 multimodal functions.

                 Finally, to complete the ASCHEA system, a new equality
                 constraint handling strategy is introduced, that
                 reduces progressively the feasible domain in order to
                 approach the actual null-measured domain as close as
                 possible at the end of the evolution.

                 The second part is a case study tackling a real-world
                 problem. The goal is to design the 2-dimensional
                 profile of an optical lens (phase plate) in order to
                 control focal-plane irradiance of some laser beam. The
                 aim is to design the phase plate such that a small
                 circular target on the focal plane is uniformly
                 illuminated without energy loss.",
