Getting Started

There are four simple steps to run an optimization problem using EvoOpt

(Example 2 from example folder)


from solver.DuelistAlgorithm import DuelistAlgorithm

**1. Define your function. Say you want to minimize the equation f=(x1,x2) = (x1)^2+(x2)^2 **

def f(x1,x2):
	return x1*x1+x2*x2

**2. Define the variables that can be manipulated for optimization. Define their names as string and put them in an array. **


3. Define the boundaries for the manipulated variables:


x1 is bounded from -2 to 10 (-2 is min value of x1 and 10 is max value of x1)

x2 is bounded from 10 to 15 (10 is min value of x2 and 15 is max value of x2)

We can arrange these boundaries according to the definition array in step 2.

Variables x1 x2
Min -2 5
Max 10 15

The corresponding code is:


4. Setup the solver and start the solve procedure.


Example Result

Numpy and Matplotlib


$python -m pip install numpy matplotlib


$pip install numpy matplotlib


You can use two methods for installation:

1. Install from github (recommended as this will download the newest version)

First download the git repository. You can do this by clicking the download button or using the git command:

$ git pull

Move to the directory:

$ cd (directory of EvoOpt)

Run setup. The following command installs all files in directory:

$ pip install -e .

**1. Install from pip **

You can install this package from pip.


$ pip install EvoOpt


$python -m pip install EvoOpt
