Dirichlet Condition
A type of boundary constraint in partial differential equation solving that directly specifies the values of the function on the boundary.
Timeline (last 90 days)
Setting the obstacle boundary to a zero Dirichlet condition causes sampled paths to terminate upon hitting a wall, thereby weakening the goal signal along long routes and making value estimates unreliable.
The PUN authors instead impose a reflecting Neumann condition on obstacles and a Dirichlet condition at the goal point, allowing sampled paths to continue exploring free space until reaching the goal, significantly improving signal propagation in long-distance navigation.
