+# N Queens Problem Solver
+
+[![CI](https://github.com/vikman90/queens-psr/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/vikman90/queens-psr/actions/workflows/ci.yml)
+
+This is a set of implementations of the famous N Queens Problem solver in
+multiple programming languages. The N Queens Problem is a problem of placing N
+queens on an NxN chessboard without any queen being able to attack the others.
+
+## Features
+
+- Efficient implementations.
+- Utilize backtracking and constraint propagation to find a solution.
+- Provides the ability to specify the number of queens (size of the board).
+- Offers an alternative testing output of the found solutions.
+
+## Performance comparison
+
+|Implementation|Steps/ms (avg)|Discards/ms (avg)|
+|--|--:|--:|
+|C++|125,20|10.715,92|
+|Rust|93,10|5.793,85|
+|Go|72,91|1.282,14|

+|C#|22,65|1.263,75|
+|Java|13,26|1.047,12|
+|Python|2,17|519,03|

+## Usage
+
+Instructions available at each implementation folder.
