 # Graph Representations and Algorithms Comparison
 
 Implementation of two graph representations and few algorithms with comparison of how fast they perform.
+
+Author: Bartosz Rodziewicz
+
+The task done as a second project for Algorithms and computational complexity (Struktury danych i złożoność obliczeniowa, yes this is official English translation).
+
+The task was to implement a way to store graphs in the app using these two representations:
+* Incidence Matrix
+* Adjacency List
+
+And implement 5 following algorithms:
+* Minimum Spanning Tree
+	* Prim's algorithm
+	* Kruskal's algorithm
+* Shortest Path
+	* Dijkstra's algorithm
+	* Bellman–Ford algorithm
+* Max Flow
+	* Ford–Fulkerson algorithm
+		* with depth-first search
+		* with depth-first and breadth-first search
+
+Using STL or Boost libraries was taken as a disadvantage.
+
+My app covers the most basic solution so I implement both ways of storing graphs using STL structures and two algorithms:
+* Prim's algorithm
+* Dijkstra's algorithm
