Linearization ofGrefers to finding a complete order of operations in V(G) that istopologically consistent with the partial order in G. This complete order corresponds toa schedule of operations on a single resource, that is, the processor. In the presence oftiming constraints, the problem of linearization can be reduced to the problem of ‘tasksequencing of variable length tasks with release times and deadlines’ which is shownto be NP-complete in the strong sense [GJ79]. It is also possible that there exists nolinearization of operations that satisfies all timing constraints. Exact and heuristic orderingschemes under timing constraints are described in [KM92a].
