What type of problems is Branch and Bound used for?

Conditions

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

Reasoning, step by step

1. Identify the nature of the problem: is it an optimization problem?
2. Determine if the objective is minimization or maximization.
3. If it is maximization, convert it to a minimization problem (e.g., by negating the objective function).
4. Apply Branch and Bound to solve the minimization problem.

Example

The instructor states, "But it is useful for solving optimization problem and only minimization problem, not maximization problem. Anyway we can convert a maximization problem into minimization and we can solve it."

Common misconceptions

• Assuming Branch and Bound can only solve minimization problems directly without conversion for maximization.
• Confusing Branch and Bound with heuristic methods that do not guarantee optimality.
