Extremal degree-based indices of general polyomino chains via dynamic programming
Manuel Montes-y-Morales, Sayle Sigarreta, Hugo Cruz-Suarez
In this paper, we develop a dynamic programming framework for identifying extremal general polyomino chains with respect to degree-based topological indices. As a concrete applicat…

Maximum augmented Zagreb index on polyomino chains
Manuel Montes-y-Morales, Saylé Sigarreta, Hugo Cruz-Suárez
In this paper, we present a dynamic programming approach for identifying extremal polyomino chains with respect to degree-based topological indices. This approach provides an expli…
