### Topsis-Aaditya-102117021
*for: Project-1(UCS654) submitted-by: **Aaditya Vardhan** Roll no: **102117021** Group: **3CS-1***
Topsis-Aaditya-102117021 is a Python library for dealing with Multiple Criteria Decision Making(MCDM) problems by using Technique for Order of Preference by Similarity to Ideal Solution(TOPSIS)
## Installation
Use the package manager **pip** to install Topsis-Aaditya-102117021
`pip install Topsis-Aaditya-102117021`
## Usage
Enter csv filename followed by *.csv* extension, then enter the *weights* vector with vector values separated by commas, followed by the *impacts* vector with comma-separated signs *(+,-)*
```bash
python sample.py sample.csv "1,1,1,1,2" "+,+,-,+,+" sample-result.csv
```
## Example
### sample.csv
A csv file showing data for different mobile handsets having varying features
| Model | Storage space (in GB) | Camera (in MP) | Price (in $) | Looks (out of 5) |
|-------|------------------------|-----------------|---------------|------------------|
| M1 | 16 | 12 | 250 | 5 |
| M2 | 16 | 8 | 200 | 3 |
| M3 | 32 | 16 | 300 | 4 |
| M4 | 32 | 8 | 275 | 4 |
| M5 | 16 | 16 | 225 | 2 |
weights vector = [1, 1, 1, 1]
impacts vector = [+,+,-,+]
### input:
`python sample.py sample.csv "1,1,1,1" "+,+,-,+" sample-result.csv`
### output:
| Topsis-score | Rank |
|-------------|------|
| 0.534277 | 3 |
| 0.308368 | 5 |
| 0.691632 | 1 |
