# PyBenchFCN

A python implementation of optimization benchmark functions (v0.0.2)

## Introduction

This library is a python implementation for the MatLab package [BenchmarkFcns Toolbox](http://benchmarkfcns.xyz/).

You can simply install with command ```pip install PyBenchFCN```.
- Pre-request: ```numpy```

## How to use

To use the package, one may see the sample code in ```Factory.py``` in the [repository](https://github.com/Y1fanHE/PyBenchFCN), or follow the script below.

```
import numpy as np

# import single objective problems from PyBenchFCN
from PyBenchFCN import SingleObjectiveProblem as SOP

n_var = 10                                      # dimension of problem
n_pop = 3                                       # size of population

problem = SOP.ackleyfcn(n_var)                  # Ackley problem

print( np.round(problem.optimalF, 5) )          # show rounded optimal value

xl, xu = problem.boundaries                     # bound of problem

x = np.random.uniform(xl, xu, n_var)            # initialize a solution
print( problem.f(x) )                           # show fitness value

X = np.random.uniform( xl, xu, (n_pop, n_var) ) # initialize a population
print( problem.F(X) )                           # show fitness values
```
