pymontecarlo

(Currently under development!) A small Python library for creating simple Monte Carlo simulations.

Installation

pip install montecarlo

Example

(See examples directory for more examples)

from montecarlo import montecarlo
from random import randint

def flip_is_heads(g):
    return randint(0, 1) == 0

mc = montecarlo(flip_is_heads)
mc.run()

Output:

Iteration #10000: 0.5079
Iteration #20000: 0.50485
Iteration #30000: 0.5059
Iteration #40000: 0.50295
...
Iteration #970000: 0.499608247423
Iteration #980000: 0.499712244898
Iteration #990000: 0.499737373737
Iteration #1000000: 0.499728

Iteration #1000000: 0.499728

Usage

The setup function passed should return a dictionary which is then passed into your test function.

The func function passed should have a single required parameter, a dictionary, which is generated by setup or empty otherwise. It should return a boolean (True for success or False otherwise).

Currently, teardown doesn't do much besides get called.

The montecarlo.run() method will also accept optional parameters iterations and print_every. The simulation will print the current probability every print_every iterations and will run for iterations iterations.
