Greedy randomized heuristic
A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time. The greedy randomized adaptive search procedure (also known as GRASP) is a metaheuristic algorithm commonly applied to combinatorial optimization problems. GRASP typically consists of iterations made up from successive constructions of a greedy randomized solution and subsequent iterative improvements of it through a local search. The greedy randomized solutions are generated by adding elements to the problem's solution set from a list of elements ranked by a …

WebGreedy Randomized Adaptive Search Procedure (GRASP) is a recently ex-ploited method combining the power of greedy heuristics, randomisation, and local search[14]. It is a multi-start two-phase metaheuristic consisting of a “con-struction phase” and a “local search phase”. The construction phase is aimed at building an initial solution ...

The construction phase of their hybrid heuristic for the Steiner problem in graphs follows the greedy randomized strategy of GRASP, while the local search phase makes use of two different neighborhood structures as a VND strategy.
