FIFO expands the first generated node (using a queue), LIFO expands the last generated node (using a stack), while Least Cost expands the node with the minimum cost (using a priority queue or similar structure based on cost).
Conditions: Used for comparing different node exploration strategies in search trees.; Applies to branch-and-bound search methods.

A path from the root records the ordered partial sequence of chosen jobs. Following a route in the drawn tree corresponds to selecting the jobs along that route in order; for example, the route using J1 then J4 means doing job 1 and job 4 and not taking jobs 2 and 3 along that partial path.
Conditions: The tree is the job-sequencing state-space tree drawn on the board.; Each edge label indicates appending one job to the current partial sequence.
