public class Offline_tca_nodeLocation extends Object implements com.net2plan.interfaces.networkDesign.IAlgorithm
Given a set of access nodes, this algorithm computes the subset of access nodes which have a core node located next to it (in the same place), and the links access-to-core nodes, so that the network cost is minimized. This cost is given by a cost per core node (C) plus a cost per link, proportional to the link euclidean distance and normalized so that the maximum link cost is one. Access-core link capacities are fixed to the user-defined parameter linkCapacities. A core node cannot be connected to more than K_max access nodes, a user-defined parameter. This problem is modeled as an ILP and optimally solved using JOM. |

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):
.class

file where the code is located, the class name,
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
