Locally optimal breaking strategy was already developed for disjoint directed circuits in the vertical constraint graph. The paper reports extensions to two classes of nondisjoint circuits: with a common vertex, and with a common path. The significance of this is that the demonstration of general applicability of the locally optimal breaking concept opens a new approach to improving the channel router heuristics for automatic and interactive routers, using parallel architectures.
