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-Deepankar-Varma-102003431==0.19

In Command Prompt

topsis 102003431-data.csv "1,1,1,1,2" "-,+,+,-,+" 102003431-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	0.71	6.7	42.1	12.59
M2	0.8	0.83	7	31.7	10.11
M3	0.7	0.62	4.8	46.7	13.23
M4	0.9	0.61	6.4	42.4	12.55
M5	0.9	0.88	3.6	62.2	16.91
M6	0.9	0.77	6.5	51.5	14.91
M7	0.9	0.44	5.3	48.9	13.83
M8	0.9	0.86	3.4	37	10.55

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.
