Roberto is using "breaking into subproblems".

A heuristic procedure, regularly called a heuristic, is any way to deal with critical thinking, learning, or revelation that utilizes a functional technique not ensured to be ideal or impeccable, but rather adequate for the prompt objectives. Where finding an ideal arrangement is unthinkable or unfeasible, heuristic techniques can be utilized to accelerate the way toward finding an agreeable arrangement.
