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…

Zagreb Connection indices on polyomino chains and random polyomino chains
Sayle Sigarreta, Hugo Cruz-Suarez
In this manuscript, we delve into the exploration of the first and second Zagreb connection indices of both polyomino chains and random polyomino chains. Our methodology relies on…

Topological indices in Random Spiro Chains
Sayle Sigarreta, Sayli Sigarreta, Hugo Cruz-Suarez
In this paper, we study topological indices in random spiro chains via a martingale approach. In which their explicit analytical expressions of the exact distribution, expected val…
