+# Knight's Shortest Path Solver
 
-The algorithm has been developed to address the following problem:
+A Python-based algorithm that finds all shortest paths for a knight on an empty chessboard.
 
-```
+## Problem Description
-A knight is in a known cell on an empty chessboard and needs to reach another known cell.
 
-Write a Python program that can take as input the two positions on the chessboard and returns as output:
+Given two positions on a standard 8x8 chessboard, this program computes:
 
-* the set of all minimum-length sequences to move the piece from the initial cell to the final cell;
+- **All minimum-length move sequences** to get a knight from the starting position to the destination
-* a graphviz/dot file of the previous "all shortest path" graph.
+- **A graph visualization** (in GraphViz/DOT format) showing all shortest paths
+
+## Features
+
+- Finds all optimal solutions (not just one)
+- Generates GraphViz DOT files for visualization
+- Containerized execution for consistency
+- Configurable output naming
+
+## Prerequisites
+
+- Docker (for containerized execution)
+- Python 3.7+ (for running directly)
+- GraphViz (optional, for rendering DOT files)
+
+## Installation & Usage
+
+### Using Docker (Recommended)
+
+Build and run the algorithm:
+
+```bash
+./run.sh build <dest_x> <dest_y> <output_name>
 ```
 
-## Getting started
+Example:
-You can build and run the algorithm using the run.sh file
+```bash
+./run.sh build 4 5 knight_paths
+```
 
-### Build
+Or use an existing image:
-To build the algorith and then run it use:
-```
-./run.sh build 4 5 test
-```
-The first element is the build or run commend that will build the container or use an already built one. then it is X and Y cordination of the destination and then the name of the output file
 
-If you do not want to build it you can use:
+```bash
+./run.sh run <dest_x> <dest_y> <output_name>
 ```
-./run.sh run 4 5 test
+
+### Parameters
+
+- `<dest_x>`: X-coordinate of destination (0-7)
+- `<dest_y>`: Y-coordinate of destination (0-7)
+- `<output_name>`: Base name for output files (no extension)
+
+### Output
+
+The program generates:
+- `<output_name>.txt`: All shortest paths in text format
+- `<output_name>.dot`: GraphViz file for visualization
+
+To visualize the graph:
+
+```bash
+dot -Tpng <output_name>.dot -o <output_name>.png
 ```

+
+## Algorithm Details
+
+The solver uses BFS (Breadth-First Search) to explore all possible knight moves, ensuring all minimum-length paths are found. It then constructs a directed graph of these paths and outputs the results in both human-readable and GraphViz formats.
