# mlrose: Machine Learning, Randomized Optimization and SEarch
mlrose is a Python package for applying some of the most common randomized optimization and search algorithms to a range of different optimization problems, over both discrete- and continuous-valued parameter spaces.

## Project Background
mlrose was initially developed to support students of Georgia Tech's OMSCS/OMSA offering of CS 7641: Machine Learning.

It includes implementations of all randomized optimization algorithms taught in this course, as well as functionality to apply these algorithms to integer-string optimization problems, such as N-Queens and the Knapsack problem; continuous-valued optimization problems, such as the neural network weight problem; and tour optimization problems, such as the Travelling Salesperson problem. It also has the flexibility to solve user-defined optimization problems. 

At the time of development, there did not exist a single Python package that collected all of this functionality together in the one location.

## Main Features

#### *Randomized Optimization Algorithms*
- Implementations of: hill climbing, randomized hill climbing, simulated annealing, genetic algorithm and (discrete) MIMIC;
- Solve both maximization and minimization problems;
- Define the algorithm's initial state or start from a random state;
- Define your own simulated annealing decay schedule or use one of three pre-defined, customizable decay schedules: geometric decay, arithmetic decay or exponential decay.

#### *Problem Types*
- Solve discrete-value (bit-string and integer-string), continuous-value and tour optimization (travelling salesperson) problems;
- Define your own fitness function for optimization or use a pre-defined function.
- Pre-defined fitness functions exist for solving the: One Max, Flip Flop, Four Peaks, Six Peaks, Continuous Peaks, Knapsack, Travelling Salesperson, N-Queens and Max-K Color optimization problems.

#### *Machine Learning Weight Optimization*
- Optimize the weights of neural networks, linear regression models and logistic regression models using randomized hill climbing, simulated annealing, the genetic algorithm or gradient descent;
- Supports classification and regression neural networks.

## Installation
mlrose was written in Python 3 and requires NumPy, SciPy and Scikit-Learn (sklearn).

The latest version can be installed using `pip`:
```
pip install -e git+git://github.com/hiive/mlrose#egg=mlrose-hiive
```
