Abstract
The present disclosure relates to a method for avoiding deadends in a constrained simulation. The method may include analyzing a first deadend during a simulation and a first constraint of the simulation. The method may further include determining if the first constraint causes the first deadend. If the first constraint causes the first deadend, the method may also include defining a first lookahead constraint corresponding to the first constraint. The method may additionally include rerunning a first previous cycle in the simulation while adding the first lookahead constraint to the simulation.
