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.",
