Document Summary
Happens for all actions regardless whether or not it is a conscious one. Unconscious planning is based on experiences and involves more heuristics. Conscious planning involves logic, rules, concepts, connections, heuristics, and computation. Identify the current state and the goal state. If goal is far, define sub-goals that can be reached from current state. Difference reduction/means-end analysis: compare where you are to where you want to be. Reduce the difference between the two states until the difference is 0. Heuristics: rule of thumb, guidance based on previous records or experiences to make a decision. Hill climbing: every step, try to maximize the desired outcome. Gradient descent: opposite of hill climbing, try to minimize loss instead. Familiarity: choose the one that you feel the most familiar with. 1/n equality: allow equal weight to each choice. Best feature: check the features between each one at a time and choose the one with the better feature.
