Simulating Ant Colony
This is an optimization algorithm and is used to find optimum solutions in a complex graph. Ants or other agents are left to explore and discover good solutions. For a game world, I think A-star algorithm is better for shortest path finding. Ant Colony Optimization The Algorithm 1. We start with a grid. Each cell…

AI Decision-making & Pathfinding in Games
Path finding Techniques Most games require AI to travel to some place; as in chasing the player intelligently or just driving along the roads to some place. For this, we need an algorithm. The algorithm we will use is called A* (read A-star). it is the most common approach used in most video games. Overview…

Pathfinding Using A* Algorithm
In a Nutshell A* algorithm for finding shortest path is, in simple words same as Dijkstra algorithm with a slight difference. In dijkstra, the algorithm considers edge cost only to determine which node to jump next. In A* however, the algorithm also considers (in addition to edge cost) an estimated value of cost from current…

Pathfinding Using Dijkstra’s Algorithm
Today, you can use Dijkstra’s pathfinding algorithm to find the shortest path from the gate to cafeteria. After understanding what it is & how exactly it works, we’ll implement it using Python. Later, we’ll implement a more better variant of it called A* algorithm. But in this post, we’ll keep ourselves to Dijkstra algorithm. If you…
