The Frog, The Broken Window, And The Resistance

The Adaptivity There is a famous phrase from Albert Einstein which says that in this world survive not the strongest individuals, even not the smartest ones but those who are the most adaptive.And that is definitely true for most situations in life. Seriously, look at the cockroaches. They're so adaptive creatures and they can survive … Continue reading The Frog, The Broken Window, And The Resistance

Sheet music creation with JavaScript

I did this as part of my Master's Degree thesis. It is a pretty old and clumsy implementation (I admit it) and I should revise and re-write it with some modern JS framework, following the good practices and principles, etc. Nevertheless, my idea was to create a unified platform for every musician, where he/she can … Continue reading Sheet music creation with JavaScript

Depth First Search (DFS) in a Graph

Depth first search is an algorithm which searches or traverses all the vertices in a graph. It starts to traverse the graph based on a start vertex. The algorithm traverses the vertices in depth. As graphs can have cycles we should not visit any visited vertex twice. For this purpose the algorithm must know if … Continue reading Depth First Search (DFS) in a Graph

Breadth First Search (BFS) in a Graph

Breadth first search is an algorithm which searches or traverses all the vertices in a graph. It starts to traverse the graph based on a start vertex. The algorithm traverses the vertices from closest ones to farthest ones. As graphs can have cycles we should not visit any visited vertex twice. For this purpose the … Continue reading Breadth First Search (BFS) in a Graph

Gale–Shapley algorithm (Stable matching)

The algorithm we are going to explain is called Gale-Shapley algorithm after mathematical economist David Gale and Lloyd Shapley who described and analyzed in 1962. In this algorithm individuals are making choices that are all individually reasonable in order to come out with a globally acceptable solution also called stable matching. Let's clarify what stable … Continue reading Gale–Shapley algorithm (Stable matching)

Dijkstra’s Algorithm

Dijkstra's algorithm is a popular algorithm created by Edsger W. Dijkstra in 1956 to find the shortest path between two vertices in a weighted graph, where edges have weight or distance which shows the distance/weight between two vertices. The algorithm has many applications in real world like in maps finding the shortest route between two locations, … Continue reading Dijkstra’s Algorithm
