FYS4150 Project 4 - Ising model

Usage

Python

usage: run.py [-h] [-s] [-p] [-an] [-z] [-r] [-a]

To run the python scripts and some the c++ files

optional arguments:
  -h, --help         show this help message and exit
  -s, --states       To get information about different states
  -p, --plot         To generate plots
  -an, --analytical  To generate analytical values
  -z, --zoom         Find maximum values and zoom
  -r, --reproduce    Reproduce the experiment as done in the report, using the same seed
  -a, --all          To run everything

C++

Compiling

make

Running

Usage
        ./runner [flags]

Options:
        -h      Show this help message
        -t      Test implementation
        -b      Finds burn-in time
        -w      Writes samples to file. Provide L, T, and seed
        -s      Finds values for L in 20, 40, 60, 80, 100, 120, 140, 160 for T in the range [2.1, 2.4]
        -z      Zooms in and finds values. Provide L, T_min, T_max and seed as system argunments
