EasyMCDM - Quick Installation methods
Install with PyPI
Once you have created your Python environment (Python 3.6+) you can simply type:
pip3 install EasyMCDM
Install with GitHub
Once you have created your Python environment (Python 3.6+) you can simply type:
git clone https://github.com/qanastek/EasyMCDM.git
cd EasyMCDM
pip3 install -r requirements.txt
pip3 install --editable .
Any modification made to the EasyMCDM package will be automatically interpreted as we installed it with the --editable flag.
Setup with Anaconda
conda create --name EasyMCDM python=3.6 -y

Instant-Runoff Multicriteria Optimization (IRMO)
Short description : Eliminate the worst individual for each criteria, until we reach the last one and select the best one.
from EasyMCDM.models.Irmo import Irmo
p = Irmo(data="data/donnees.csv", verbose=False)
res = p.solve(
indexes=[0,1,4,5], # price -> max_speed -> comfort -> trunk_space
prefs=["min","max","min","max"]
)
print(res)
Output :
{'best': 'saab_tid'}
