In this lecture segment, backtracking is described as depth-first search, while branch and bound is described as breadth-first search. Backtracking goes down one branch to the next level before considering siblings, whereas branch and bound considers all alternatives at the current level first.

Conditions: Applied to a state-space tree for job sequencing.; The comparison is about exploration order, not about bounding rules or cost evaluation.

A solution can be represented in two main ways: as a variable-size subset of selected jobs (e.g., $S1 = {J_1, J_4}$), or as a fixed-size binary vector where each position corresponds to a job and the value indicates whether the job is done (1) or not (0) (e.g., $S2 = {1, 0, 0, 1}$).

Conditions: The problem involves selecting a subset of jobs from a given set.; The representation must clearly indicate which jobs are included in the solution.

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.

Branch and Bound is primarily used for solving optimization problems, specifically minimization problems. Maximization problems can be converted into minimization problems to be solved using this method.

Conditions: The problem is an optimization problem.; The method is applied to find the optimal solution (minimum or maximum).

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 $J_1$ then $J_4$ 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.
