find optimal optimal path for drones in a grid of assigned values

solution1

• written in java
• single drone solution
• employs a floodfill algorithm
• where possible paths are always sorted in descending order of value (so far) of the points in the path
• and which uses backtracking to find alternative paths that may be of higher value
• non-recursivity ensures no issues for large grids
• the algorithm is embedded in a rest api
• it also has a html canvas frontend that draws the path on the grid

running:

• install jdk22, and apache maven
• run mvn spring-boot:run
• go to http://localhost:8080
• in the console in the ui type fly [enter]
• input values for the algorithm can be updated, eg T=2000 or x=10 etc.
• use clear to refresh

solution2

• written in rust
• single and multiple drones
• uses basically the same method, but after a definitive flight path is calculated, the grid is updated for the next drone
• see tests and main for validity of the algorithm
