# Package Description

_This package is built as a submission to_ [Assignment 1](https://github.com/psrana/Assignment-Topsis)

_Submitted by:_ **Shivank Bhatia (102303655), 3C45**

*Definition:*
TOPSIS, acronym for Technique for Order Preference by Similarity to Ideal Solution, is a multi-criteria decision-making (MCDM) method used to rank alternatives by selecting the option that is closest to the ideal solution and farthest from the worst (negative ideal) solution.

## ✅ **Installation**

Use the package manager pip to install topsis-shivank-102303655
```bash
pip install topsis-shivank-102303655==0.2.2
```

## ⚙️ **Usage**
```bash
topsis data.csv 1,1,1,1,1 +,+,-,+,+ result.csv
```
where,
- **data.csv** is your input file  
- Weights to be assigned to each feature  
- Impacts to optimize each feature (`'+'`: Maximize, `'-'`: Minimize)  
- Output file path to save the results

## 🗒️ **Notes**
### The package handles the following:
- Correct number of parameters (inputFileName, Weights, Impacts, resultFileName).
- Show the appropriate message for wrong inputs.
- Handling of “File not Found” exception
- The input file must contain three or more columns.
- From 2nd to last columns must contain numeric values only (Handling of non-numeric values)
- The number of weights, number of impacts and number of columns (from 2nd to last columns) must be the same.
- Impacts must be either +ve or -ve.
- Impacts and weights must be separated by ‘,’ (comma).
