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-Kunal-102053007

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	0.66	0.44	4.9	32.9	9.73
M2	0.65	0.42	5	44.5	12.64
M3	0.61	0.37	3.3	41.1	11.35
M4	0.62	0.38	6.5	64.1	17.9
M5	0.83	0.69	6.4	34.4	10.58
M6	0.88	0.77	6.7	34.8	10.79
M7	0.63	0.4	4.5	39.1	11.16
M8	0.8	0.64	4.4	45.7	12.89

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.
