Open BEAGLE is a C Evolutionary Computation (EC) ...

open BEAGLE by Christian Gagne is a C Evolutionary Computation (EC) framework. It provides an high-level software environment to do any kind of EC, with support for tree-based genetic programming; bit string, integer-valued vector, and real-valued vector genetic algorithms; and evolution strategy.
The open_beagle 3.0.1 architecture follows strong principles of object oriented programming, where abstractions are represented by loosely coupled objects and where it is common and easy to reuse code. Open BEAGLE [openbeagle3.0.1.exe] is designed to provide an EC environment that is generic, user friendly, portable, efficient and robust.
Object-Oriented Foundations:
- Modern C programming approach
- Structured OO architecture
- Smart pointers for automatic memory allocation management
- XML file formats with built-in parsing facility
- Sophisticated logging mechanism with output in XML
- Parameters and algorithms dynamically configurable by files
- Generic representation of the algorithms using a plug-in mechanism
- Milestone mechanism for evolution recovery and results analysis
Open BEAGLE - 0MB generic EA framework:
- Many predefined operators
- Generational, steady-state, (mu, lambda), and (mu lambda) replacement strategies
- Population composed of multiple demes
- Individuals represented on multiple genomes
- History of best-of-run individuals for the whole population and for each demes
- Complete evolution statistics
- Multiobjective optimization (currently NSGA-II and NPGA2)
- Population seeding from file
GA framework (linear representations):
- Bit string GA representation with decoder functions (binary and Gray-coded)
- Integer-valued vector GA representation
- Real-valued vector GA representation
- Evolution strategy (ES)
- Covariance Matrix Adaptation ES (CMA-ES)
- Three generic crossover operators (one-point, two-points, uniform) and two float vector specific operators (BLX-alpha and SBX)
- Four specific mutation operators
- Operators for shuffled indices genotypes for the integer-valued vector representation
- Seven illustrative examples (OneMax, ZeroMin (OneMax minimization), Function Maximization with Bit String GA, Function Maximization with Real-Valued GA, Function Maximization with ES, Multiobjective 0/1 Knapsack, Travelling Salesman Problem)
GP framework:
- Standard crossover operator
- Five mutation operators: standard (Koza GP I) mutation, swap node mutation, shrink mutation, swap subtree mutation, and random ephemerals value mutation
- Three initializations method for trees: full, grow, and half-and-half; each ramped or not
- Abstract primitive class
- Many predefined primitives
- Automatically defined functions (ADF)
- Random ephemeral constants
- Constrained GP tree operators with support for strongly-typed genetic_programming
- Three illustrative examples (Symbolic Regression, Even 6-Parity, and Spambase)
Co-evolution framework:
- Co-evolution support based on multi-threading
- Multi-threading classes incapsulating OS-specific calls
- Co-evolutionary fitness evaluation operator for basic EC and GP
- Two illustrative examples (Two-Populations Iterated Prisoner's Dilemma, Co-evolutionary Symbolic Regression)
