binary firefly algorithm MATLAB code for optimization

Description

Original firefly algorithm uses a real number as position. If you are going to use it for an optimization problem that needs a binary position, you must change it.

We change the original firefly algorithm to work by binary position, so you can use this code in your project such as :
Feature selection by firefly optimization algorithm
feature reduction by firefly optimization algorithm
attribute selection by firefly optimization algorithm
attribute reduction by firefly optimization algorithm

You can define other cost function easily.
