Abstract
Techniques for establishing the sufficiency of a path planner to avoid multiple obstacles in planning a path from a starting location to a destination location is presented. The techniques can include: iterating, until a stopping condition occurs: obtaining, from the path planner, a path from the starting location to the destination location; representing the path from the starting location to the destination location as a disjunction of logical terms; conjoining the disjunction of terms to a conjunction of terms representing previously considered paths; determining a satisfiability condition of the conjunction of terms; and for a positive satisfiability condition, adding at least one corresponding obstacle of the plurality of obstacles to the path planner; and providing an indication of sufficiency of the path planner to avoid the obstacles in planning a path from the starting location to the destination location based on the stopping condition.
