Minimize Final Time with ODE Time Scaling

A differential equation is time-scaled by dividing the differential term by a final time scaling factor. This approach is useful in dynamic optimization or optimal control problems where the final time is not known but final conditions may need to be satisfied. The Jennings optimal control problem is used to demonstrate minimum time optimization. See apmonitor.com/do/index.php/Mai... for source code.

Hi! First of all thanks for your videos, they are very helpful. I have a problem with solving gekko task: i need to find the right parameters (a, b, c) to maximize u(t) = y / (x+y). I also have \dot x and \dot y equations. Maybe u can help me with a hint of how to do it?
