BSD](https://img.shields.io/badge/license-BSD-green)\n![language - MATLAB](https://img.shields.io/badge/language-MATLAB-blue)\n![category - science](https://img.shields.io/badge/category-science-lightgrey)\n![status - unmaintained](https://img.shields.io/badge/status-unmaintained-red)\n\nThis **MATLAB toolbox** can be used for the following problems:\n* finding **global minimum** of a function\n* **fitting a function** to a dataset\n\nThis toolbox is specially adapted to the **following problems**:\n* **non-smooth** error function\n* **non-convex** error function\n* **computationally heavy** error function\n* error function with **local minima**\n* error function with **many input variables**\n\nThis toolbox provides a common interface for **different solvers**:\n* **gradient**: fminunc / fmincon\n* **simplex**: fminsearch\n* **surrogate**: surrogateopt\n* **evolutionary**: particleswarm / ga\n* the aforementioned solvers can be **combined**\n\nCustomized **error function**:\n* custom **weights** for the dataset points\n* choice of the **error metric** (norm, average, percentile, etc.)\n* recover from **undefined values**\n* **vectorized evaluation** of the error function\n* **parallel evaluation** of the error function\n* **caching** of the error function\n\nAdvanced **variable handling**:\n* **abstraction layer** for the variables\n* **initial** values\n* **scalar or vector** variables\n* variable **transformation** (linear, quadratic, logarithmic, etc.)\n* variable **normalization**\n* **constraints** (lower and upper bounds)\n* **sine transformation** for handling constraints\n\nAdvanced **monitoring** capabilities:\n* compute various error metrics\n* compute solver figures of merit\n* plot/display the solver progress\n* plot/display the final results\n\n## Limitations\n\n* All the provided features have a **computational cost**.\n* Therefore, this library is mostly adapted to **time-consuming error functions**.\n* For simple error functions, the **overhead is non-negligible**.\n\n## Examples\n\n* [run_example_fitting.m](run_example_fitting.m) - Simple fitting of a model with respect to a dataset.\n* [run_example_optim.m](run_example_optim.m) - Find the global minimum of a function.\n\n\u003cp float=\"middle\"\u003e\n    \u003cimg src=\"readme_img/convergence.png\" width=\"350\"\u003e\n    \u003cimg src=\"readme_img/histogram.png\" width=\"350\"\u003e\n\u003c/p\u003e\n\n## Compatibility\n\n* Tested with MATLAB R2021a.\n* The `gads_toolbox` is required (for the MATLAB solvers).\n* The `optimization_toolbox` is required (for the MATLAB solvers).\n* The `distrib_computing_toolbox` is required (for parfor loops)\n* Compatibility with GNU Octave not tested but probably problematic.\n\n## Author\n\n**Thomas Guillod** -
