fig_sec11_7_modularCapacitiesAndRouting_dualDecomp.m
MATLAB file used for generating the graph/s of the case study in the
book using this algorithm.Given a network with a set of given nodes, and links, and a given known unicast offered traffic. This algorithm jointly computes (i) the routing of the traffic, and the capacity to assign to the links. The link capacities are constrained to be modular: an integer multiple of a link capacity quantum. Optimization target is minimizing the network cost, given by the number of capacity modules to install in the network. The problem in NP-hard. The algorithm implements a dual decomposition iterative, using a subgradient algorithm. |

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
