+examine them, and then create a path. Instead, Soar is in a specific state at a given time
 (represented in working memory), attempting to select an operator that will move it to a
 new state. It uses whatever knowledge it has about selecting operators given the current
 situation, and if its knowledge is sufficient, it will move toward its goal.
