Table Summary

Core Terminology

Master key academic terminology through active recall and spaced repetition concepts.

Aggregation

Grouping indistinguishable individual objects into numerical quantities to reduce planning complexity.

O(Nb)

What is the computational complexity of the critical path algorithm for N actions and max branching factor b?

Minimum Slack

The _____ algorithm schedules the unscheduled action with all predecessors finished that has the least slack first.

Intersects

A high-level plan achieves a goal in angelic semantics if its reachable set _____ the set of goal states.

Optimistic

Under angelic search, if the _____ reachable set for a plan doesn't intersect the goal, the plan is definitely unworkable.

Contingency planning

Generating plans with conditional branches based on percepts to handle partial observability and nondeterminism.
