Webinformation graph can affect the capacity region. Their question is captured formally by the notion of criticality of an edge. Deﬁnition 1. Given an index coding problem G = (V,E), an edge e∈Eis said to be critical if the removal of efrom Gstrictly reduces the capacity region. Deﬁnition 2. The index coding problem G=(V,E)is Web1 de nov. de 2024 · The utility of the inner bound is demonstrated by examples that include the capacity region for all index coding problems with up to five messages (there are … WebNext, we deﬁne a code-constrained capacity region that restricts attention to any pre-speciﬁed set of coding actions. A dynamic max-weight algorithm that acts over variable length frames is developed. The algorithm allows for random packet arrivals and supports any trafﬁc inside the code-constrained capacity region. twisted arm menu sarnia
