Pyswarms

~~~~~~~~~~~~~~~~~~

* **NEW:** Native GridSearch and RandomSearch implementations for finding the best hyperparameters in controlling swarm behaviour - `4`_, `20`_, `25`_. Contributed by `SioKCronin <https://github.com/SioKCronin>`_. Thanks a lot!
* **NEW:** Added tests for hyperparameter search techniques - `27`_, `28`_, `40`_. Contributed by `jazcap53 <https://github.com/jazcap53>`_. Thank you so much!
* **IMPROVED:** Updated structure of Base classes for higher extensibility

* **NEW:** Binary Particle Swarm Optimization - `7`_, `17`_
* **FIX:** Fix on Ackley function return error - `22`_
* **IMPROVED:** Documentation and unit tests - `16`_

* **FIX:** Patch on LocalBestPSO implementation. It seems that it's not returning the best value of the neighbors, this fixes the problem .
* **NEW:** Test functions for single-objective problems - `6`_, `10`_, `14`_. Contributed by `Carl-K <https://github.com/Carl-K>`_. Thank you!

------------------

* First release on PyPI.
* **NEW:** Includes primary optimization techniques such as global-best PSO and local-best PSO - `1`_, `3`_
