A Hierarchical Evolutionary-Deterministic Algorithm in Topological Optimization of Electrical Grounding Grids [PDF]

, 2005
This paper proposes a Hierarchical Evolutionary-Deterministic Algorithm (HEDA) for designing square grounding grids. This algorithm performs the design by means of a hierarchical coupling of a real coded evolutionary algorithm and the Hooke-Jeeves algorithm. The design of the grounding grid is here formalized as a min-max problem. The maximization part
