here. for the sake of discussion, we have (let's take seemingly missing data from problem #1):

raptors attack accelerating at 4 m/s^2 up to their top speed of 25 m/s. you're at the center of equilateral triangle with a raptor at each corner. the top raptor has a wounded leg and is limited to a top speed of 10 m/s. you begin to flee, quickly (1) reaching your top speed of 6 m/s. the raptor will run towards you. at what angle (2) you should run to maximize the time you stay alive?

three problems with that is (1) what does "quickly" mean (∞ m/s^2 ?), then (2) who said that straight line is the optimal route to take, and (3) should everyone keep running at their top speed once it was reached?

how would you go about solving this problem? I am tempted to write simple "genetic" solver based on brute-force simulation.
