public class Offline_fa_ospfWeightOptimization_GRASP extends Object implements com.net2plan.interfaces.networkDesign.IAlgorithm
fig_sec12_7_ospfWeightGRASP.m
MATLAB file used for generating the graph/s of the case study in the
book using this algorithm.Given a set of nodes, links and offered traffic, this algorithm assumes that the nodes are IP routers running the OSPF protocol (applying ECMP rules) for routing it. The algorithm searches for the set of link weights that optimize the routing. In particular, the target is minimizing a congestion metric computed as a function of both the worst-case link utilization and the average link utilization. The algorithm is based on applying a GRASP heuristic approach (Greedy Randomzied Adaptive Search Procedure). |

Returns the list of required parameters, where the first item of each element is the parameter name, the second one is the parameter value, and the third one is the parameter description.
It is possible to define type-specific parameters if the default value is set according to the following rules (but user is responsible of checking in its own code):

and a set of parameters (pair of key-values separated by commas, where individual
key and value are separated with an equal symbol. The same applies to reports (#report#),
event generators (#eventGenerator#) and event processors (#eventProcessor#).getParameters
