Gnowee is a general purpose hybrid metaheuristic optimization algorithm designed for rapid convergence to nearly globally optimum solutions for complex, constrained engineering problems with mixed-integer and combinatorial design vectors and high-cost, noisy, discontinuous, black box objective function evaluations. Gnowee's hybrid metaheuristic framework is based on a set of diverse, robust heuristics that appropriately balance diversification and intensification strategies across a wide range of optimization problems. Comparisons between Gnowee and several well-established metaheuristic algorithms are made for a set of eighteen continuous, mixed-integer, and combinatorial benchmarks. A summary of these benchmarks is available. These results demonstrate Gnoweee to have superior flexibility and convergence characteristics over a wide range of design spaces.
A paper, describing the Gnowee framework and benchmarks is available
For examples on how to run Gnowee, please refer to the runGnowee notebook included in the src directory. This contains multiple examples of how to modify and run Gnowee.
To build the documentation, in the docs/src directory run the command:
>> doxygen Doxyfile
This will build the html and latex version of the documentation. The symlink in the docs directory for the html index should automatically update. If not the html index can be found here.
The up-to-date latex documentation is included in pdf form. If an update of the latex documentation is desired, go to the docs/latex directory and run the command:
>> make
This will build the latex documentation. The updated documentation file will be named refman.pdf and be placed in this directory.
