The Perfect Sorting Algorithm

Simon showed us this guessing game where we had to guess the correct sequence of cards with numbers 1, 2, 3, 4 while the cards are all flipped upside down. … Continue reading The Perfect Sorting Algorithm

The Diffe-Hellman key exchange algorithm

This is Simon explaining Diffe-Hellman key exchange (also called DiffeHellman protocol). He first explained the algorithm mixing watercolours (a color representing a key/ number) and then mathematically. The algorithm allows … Continue reading The Diffe-Hellman key exchange algorithm

Why mathematics may become computer science

Walking home from the swimming pool (where he and Neva had been jumping into the water exactly 24 times, calling out all the permutations of 1,2,3 and 4), Simon suddenly … Continue reading Why mathematics may become computer science

Simon’s new “giant project”: Sorting Visualizations

Simon writes: I’ve built a giant project; a website / community project / platform for making algorithms! I’ve built in this video Bubble Sort, Selection Sort, Insertion Sort, Mergesort, Quicksort, … Continue reading Simon’s new “giant project”: Sorting Visualizations

Pathfinding algorithms: Dijkstra’s and Breadth-first search

The photos below show Simon playing with Breadth-first search and Dijkstra’s algorithms to find the most efficient path from S to E on a set of graphs. The two more … Continue reading Pathfinding algorithms: Dijkstra’s and Breadth-first search
