We had to improve the metaheuristic benchmarking those functions in 10 and 30 dimension.\n\n\n## License\nAll the work is licensed in GPL, except the [function data](src/cec2014_data) and [definitions](src/cec2014_func.cpp) that weren't originally licensed by their author (no copyright violation intended, all the work done has educational purposes).\n\n## Usage\nIn `src` folder, do `cmake .` and `make`. Realea software by Daniel Molina has been used, and the structure of the algorithm has been implemented in `metaheuristic.(h/cc)`. The parameters of the algorithm can be modified in `aux.h` and `aux.cc`. For further documentation check [memoria](doc/memoria.tex).\n\n## Improvements\n\nOriginal results of implementation of metaheuristic as described by their authors (such definition can be consulted in [memoria](doc/memoria.tex)):\n\n\n\n|   |**D=10**|**D=30**|\n|:--|-------:|-------:|\n|f1|19084554.669857|78738913.351420|\n|f2|16536.801547|13697676.211767|\n|f3|21065.221623|77800.939852|\n|f4|58.764875|246.343748|\n|f5|20.170120|20.468675|\n|f6|7.539682|34.790689|\n|f7|0.861159|1.102618|\n|f8|28.934028|129.837295|\n|f9|26.123286|145.730468|\n|f10|1157.285877|4219.909911|\n|f11|1144.876264|4881.285910|\n|f12|0.661762|1.304201|\n|f13|0.456650|0.440387|\n|f14|0.635537|0.260939|\n|f15|4.164066|51.414376|\n|f16|3.390798|12.366670|\n|f17|236940.300926|3390125.155789|\n|f18|6522.070266|110104.005591|\n|f19|8.886340|32.516194|\n|f20|13892.000148|53412.013643|\n\nAfter the several improvements done:\n\n|   |**D=10**|**D=30**|\n|:--|:-------|:-------|\n|f1|0.000000|153.994848|\n|f2|0.000000|0.000000|\n|f3|0.000000|0.000000|\n|f4|0.000000|0.147572|\n|f5|20.001247|20.622110|\n|f6|0.000002|0.357917|\n|f7|0.000000|0.000000|\n|f8|4.576812|27.580246|\n|f9|4.576811|27.699639|\n|f10|283.681734|1693.500771|\n|f11|299.088276|2233.018358|\n|f12|0.029925|0.019306|\n|f13|0.044096|0.169150|\n|f14|0.275749|0.281541|\n|f15|0.566455|2.281242|\n|f16|3.267757|13.005128|\n|f17|252.999183|1340.708149|\n|f18|44.665859|286.135882|\n|f19|1.593592|11.621429|\n|f20|49.247290|505.252065|\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fncordon%2Fion-algorithm","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fncordon%2Fion-algorithm","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fncordon%2Fion-algorithm/lists"}
