with due attention towards their structure is achieved through graph theory. A directed graph (digraph) of the service … interrelationships. A matrix, which is equivalent to the digraph, is established that will generate a service quality function that will …

consider two extensions of this problem: The subset sum problem with digraph constraint (SSG) and subset sum problem with weak … digraph constraint (SSGW). In both problems there is given a digraph with sizes assigned to the vertices. Within SSG we want … provide pseudo-polynomial solutions for SSG and SSGW with digraph constraints given by directed co-graphs and series …
