The present invention relates to an automatic method of computerized optimization of a technical system like for instance routing systems such as a transportation routing system or a communication network.;The invention teaches an optimization method of a technical system comprising new ruin- and recreate-steps operating on the state-variables of a current system state. The ruin-step destroys the current state in a larger extend and thus introduces increased freedom for the recreate-step to create a new state. This allows for recalculating a new state in accordance with additional constraints which also improves a quality measure of the state; i.e. every recalculated state always fulfills the additional constraints. Moreover, the recreate-step is not guided by the values of said destroyed state variables, which opens a larger space for determining a new state.
