Greedy vs backtracking

WebAccording to the bounding values, we either stop there or extend. Applications of backtracking are n-Queens problem, Sum of subset. Applications of branch and bound are knapsack problem, travelling salesman problem, etc. Backtracking is more efficient than the Branch and bound. Branch n bound is less efficient. WebAdjective.

WebGreedy: As Many As Possible (longest match) By default, a quantifier tells the engine to match as many instances of its quantified token or subpattern as possible. This behavior is called greedy. For instance, take the + quantifier. It allows the engine to match one or more of the token it quantifies: \d+ can therefore match one or more digits.
