Query: A Cumulative Multi-Niching Genetic Algorithm for Multimodal Function
  Optimization   This paper presents a cumulative multi-niching genetic algorithm (CMN GA),
designed to expedite optimization problems that have computationally-expensive
multimodal objective functions. By never discarding individuals from the
population, the CMN GA makes use of the information from every objective
function evaluation as it explores the design space. A fitness-related
population density control over the design space reduces unnecessary objective
function evaluations. The algorithm's novel arrangement of genetic operations
provides fast and robust convergence to multiple local optima. Benchmark tests
alongside three other multi-niching algorithms show that the CMN GA has a
greater convergence ability and provides an order-of-magnitude reduction in the
number of objective function evaluations required to achieve a given level of
convergence.
