Study Notes
Robot Navigation
- Aims to solve the problem of finding a path from a start position to a goal position in a given environment
Map Representation
- Maps are represented in computer systems using graphs, which are a set of nodes connected by edges
Breadth-first Graph Search
- Finds the shortest path to the goal, but it may not be the best path
- The main difference between the path found using Breadth-first Graph Search and the best path is that the latter takes into account additional factors such as distance, time, and cost
Uniform Cost Search
- Expands the frontiers based on the cost of reaching each node, i.e., the cheapest nodes are expanded first
A* Search
- Uses an admissible heuristic function to determine the next step, which helps to guide the search towards the goal and find the shortest path
