Dear Mathematica community,
I am pretty new with using Mathematica. So, maybe there is a very
obvious solution to my problem that I missed to find out myself.
I am trying to solve a problem that is setup like that:
The cost function ec[t] depends on cumulative arrivals R[t]. At a
variable starting point tstart (for which i try to find a cost-
minimizing value in a NMinimize fct), cumulative arrivals are 0.
But obviously, the derivative of R[tstart] goes to infinity, which is
why no solution can be found.
Thanks for helpful comments!
