0.1.0 (2017-07-12)

  • First release on PyPI.
  • Includes primary optimization techniques such as global-best PSO and local-best PSO - #1, #3

0.1.1 (2017-07-25)

  • Patch on LocalBestPSO implementation. It seems that it's not returning the best value of the neighbors, this fixes the problem .
  • New feature: Test functions for single-objective problems - #6, #10, #14. Contributed by @Carl-K. Thank you!

0.1.2 (2017-08-02)

  • New feature: Binary Particle Swarm Optimization - #7, #17
  • Patch on Ackley function return error - #22
  • Improved documentation and unit tests - #16

0.1.4 (2017-08-03)

  • Added a patch to fix pip installation

0.1.5 (2017-08-11)

  • New feature: easy graphics environment. This new plotting environment makes it easier to plot the costs and swarm movement in 2-d or 3-d planes - #30, #31

0.1.6 (2017-09-24)

  • New feature: Native GridSearch and RandomSearch implementations for finding the best hyperparameters in controlling swarm behaviour - #4, #20, #25. Contributed by @SioKCronin. Thanks a lot!
  • Added tests for hyperparameter search techniques - #27, #28, #40. Contributed by @jazcap53. Thank you so much!
  • Updated structure of Base classes for higher extensibility

0.1.7 (2017-09-25)

  • Fixed patch on local_best.py and binary.py - #33, #34. Thanks for the awesome fix, @CPapadim!
  • Git now ignores IPython notebook checkpoints

0.1.8 (2018-01-11)

  • PySwarms is now published on the Journal of Open Source Software (JOSS)! You can check the review here. In addition, you can also find our paper in this link. Thanks a lot to @kyleniemeyer and @stsievert for the thoughtful reviews and comments.

0.1.9 (2018-04-20)

  • You can now set the initial position wherever you want - #93
  • Quick-fix for the Rosenbrock function - #98
  • Tolerance can now be set to break during iteration - #100

Thanks for all the wonderful Pull Requests, @mamadyonline!

0.2.0 (2018-06-11)

  • New PySwarms backend. You can now build native swarm implementations using this module! - #115, #116, #117
  • Drop Python 2.7 version support. This package now supports Python 3.4 and up - #113
  • All tests were ported into pytest - #114

0.2.1 (2018-06-27)

0.3.0 (2018-08-10)

  • New topologies: Pyramid, Random, and Von Neumann. More ways for your particles to interact! - #176, #177, #155, #142. Thanks a lot @whzup!
  • New GeneralOptimizer algorithm that allows you to switch-out topologies for your optimization needs - #151. Thanks a lot @whzup!
  • All topologies now have a static attribute. Neigbors can now be set initially or computed dynamically - #164. Thanks a lot @whzup!
  • New single-objective functions - #168. Awesome work, @jayspeidell!
  • New tutorial on Inverse Kinematics using Particle Swarm Optimization - #141. Thanks a lot @whzup!
  • New plotters module for visualization. The environment module is now deprecated - #135
  • Keyword arguments can now be passed in the optimize() method for your custom objective functions - #144. Great job, @bradahoward

0.3.1 (2018-08-13)

  • New collaboration tool using Vagrantfiles - #193. Thanks a lot @jdbohrman!
  • Add configuration file for pyup.io - #210
  • Fix incomplete documentation in ReadTheDocs - #208
  • Update dependencies via pyup - #204
