Python Turtle – Morphing Algorithm
Tweening/Morphing effects are often used in Computer Animations to change the shape of an object by morphing an object from one shape into another. In tweening, key frames are provided and “in-between” frames are calculated to make a smooth looking…
Machine Learning – Top Trumps Game
The purpose of this post is to demonstrate a basic example of how machine learning works. In this example, the computer learns how to play a game of Top Trumps more effectively to increase its chance of winning the game.…
Heuristic Approaches to Problem Solving
“A heuristic technique, often called simply a heuristic, is any approach to problem solving, learning, or discovery that employs a practical method not guaranteed to be optimal or perfect, but sufficient for the immediate goals. Where finding an optimal solution…
A* Search Algorithm
The A* Search algorithm (pronounced “A star”) is an alternative to the Dijkstra’s Shortest Path algorithm. It is used to find the shortest path between two nodes of a weighted graph. The A* Search algorithm performs better than the Dijkstra’s…
Dijkstra’s Shortest Path Algorithm
Dijkstra’s Shortest Path Algorithm is an algorithm used to find the shortest path between two nodes of a weighted graph. Before investigating this algorithm make sure you are familiar with the terminology used when describing Graphs in Computer Science. Let’s…
Boolean Algebra
In this blog post we are investigating different formulas than can be used to simplify a Boolean expression. Double Negation ¬ ¬A = A Complement Laws A ∧ ¬A = 0 A ∨ ¬A = 1 Idempotent Laws A ∧…
Big O Notation
The question we will try to answer in this blog post is as follows: How can we measure the effectiveness/performance of an algorithm? First let’s consider this quote from Bill Gates (Founder of Microsoft): “Measuring programming progress by lines of…
