WebMay 29, 2024 · In this section, we consider polynomial time algorithms for solving Tracking Paths for chordal graphs and tournaments. We start by giving a polynomial time algorithm for finding a tracking set for undirected chordal graphs. Recall that chordal graphs are those graphs in which each cycle of length greater than three has a chord. WebThe converse to the last statement also explains part of the interest in ${\sf NP}$-completeness among algorithm designers: if ${\sf P} \neq {\sf NP}$ (as is widely believed), then it means that no problem that corresponds to an ${\sf NP}$-hard language can be solved by any polynomial-time algorithm.
