What is TOPSIS?

Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) originated in the 1980s as a multi-criteria decision making method. TOPSIS chooses the alternative of shortest Euclidean distance from the ideal solution, and greatest distance from the negative-ideal solution.

How to install this package:

>> pip install Topsis-Pranav-102003432

In Command Prompt

>> topsis data.csv "1,1,1,1,1" "+,+,-,+,-" result.csv

Input file (data.csv)

The decision matrix should be constructed with each row representing a Model alternative, and each column representing a criterion like Accuracy, R², Root Mean Squared Error, Correlation, and many more.

Model	P1	P2	P3	P4	P5
M1	0.7	0.5	7	37	11.3
M2	0.8	0.6	7	46	13.4
M3	0.7	0.5	7	48	14
M4	0.9	0.8	7	44	13.2
M5	0.9	0.9	5	37	11.1
M6	0.9	0.6	3	67	18
M7	0.9	0.5	7	39	11.8
M8	0.9	0.9	5	46	13.2

Weights (weights) is not already normalised will be normalised later in the code.

Information of benefit positive(+) or negative(-) impact criteria should be provided in impacts.
