| Rezumat | ||||||
We present a technique to solve numerically minimization problems with equality constraints. We focus on problems with a great number of local minima which are hard to obtain by local minimization algorithms with random starting guesses, making it difficult to find the global minimum. The described technique has been applied to search 10th-order optimized time-symmetric composition integrators. By applying our technique, we are able to obtain 10th order integrators with smaller 1-norm than any other integrator found in the literature up to now. |
