G+ is a common Genetic Algorithm control developed as part of my MSc dissertation. It is a language independent component which means it can be used in any language such as VB and Delphi, as long as it supports COM standard. G+ is developed based on the famous C++ library GAlib. It is free. Licensing and copyright details are available.
G+ provides the user with a great flexibility by allowing a variety of user defined operators. The main features of G+ are listed below:
Data types: binary, real or integers
Algorithm types: Simple GA (SGA), Steady State, Crowding GA.
Selection Operators: Roulette Wheel, Tournament, Rank, Uniform, SRS (Stochastic remainder sampling) Selection, Deterministic Sampling Selection, and user defined selection.
Crossover Operator: Single-point, Two-point, Uniform crossover, Even-Odd Crossover, Partial-Match, Order Crossover, Cycle Crossover, and user defined crossover.
Mutation Operators: Flip Mutation, Swap Mutation, Gaussian Mutation, and user defined mutation
Termination Method: Maximum generations, Convergence, and user defined termination.
Initializer: .Random Initializer, Ordered Initializer, and user defined Initializer.
The G+ control can be downloaded from this web site with examples and documentations. It has been tested under various problems such as multi-variable mathematical functions and TSP problems. The result shows that G+ is a very powerful tool for using genetic algorithms to do optimization tasks.
The the instructions for distribution of G+ are also available on this web site.
