Memetic Algorithms

2016
Memetic algorithms provide one of the most effective and flexible metaheuristic approaches for tackling hard optimization problems. Memetic algorithms address the difficulty of developing high-performance universal heuristics by encouraging the exploitation of multiple heuristics acting in concert, making use of all available sources of information for

A differential memetic algorithm

Artificial Intelligence Review, 2012
Memetic algorithms have been devised to rectify the absence of a local search mechanism in evolutionary algorithms. This paper proposes a differential memetic algorithm (DMA). To this end, first we propose a differential bidirectional random search as a local search algorithm.

Memetic algorithms for timetabling

The 2003 Congress on Evolutionary Computation, 2003. CEC '03., 2004
Course timetabling problems are real world constraint optimization problems that are often coped with educational institutions, such as universities or high schools. In this paper, we present a variety of new operators that can be also applied in evolutionary algorithms for other timetabling problems, such as, exam timetabling.

Adaptive Cellular Memetic Algorithms

Evolutionary Computation, 2009
A cellular genetic algorithm (CGA) is a decentralized form of GA where individuals in a population are usually arranged in a 2D grid and interactions among individuals are restricted to a set neighborhood. In this paper, we extend the notion of cellularity to memetic algorithms (MA), a configuration termed cellular memetic algorithm (CMA). In addition,

Memetic Algorithms

2007
The term memetic algorithms (MAs) was introduced in the late 1980s to denote a family of metaheuristics that have as central theme the hybridization of different algorithmic approaches for a given problem. Special emphasis was given to the use of a population-based approach in which a set of cooperating and competing agents was engaged in periods of ...

Formal memetic algorithms

1994
A formal, representation-independent form of a memetic algorithm—a genetic algorithm incorporating local search—is introduced. A generalised form of N-point crossover is defined together with representation-independentpatching and hill-climbing operators.
