Hi All,

I am working on a problem of optimal control of mobile robot. I am facing a 1st order ode with 8 unknowns. I tried RK and Stiff solver in NRC. But I got the same answer: Too many steps in odeint. I can see from the print statements I placed in that the step size is getting smaller and smaller. The strangest thing is that I know the solution ode already. I solved the same equations with relaxation method also in NRC for two point boundary value problem with half of the boundary conditions specific at the end of time. But I just can't get anything from RK or stiff. I have been trying for a month in my spare time without successful. Can anyone help me here ?

Thanks for reading.
