In this model, the failure of a node causes the deletion of its closed neighborhood, i.e., the node and its adjacent neighbors as well. The minimum number of closed neighborhoods whose removal results in an empty, complete, or disconnected subgraph is called the neighbor-connectivity of the graph. Since then component order connectivity models have emerged to address inadequacies in the traditional models of connectivity, namely, that in many real-world networks, when disconnecting a graph one may be left with components that are large enough to still be operable. By adapting neighbor-connectivity to a component order model, we introduced neighbor-component order connectivity, defined as the minimum number of closed neighborhoods that must be removed from a network to ensure all remaining components have order less than some given threshold value. Given a threshold value of one, the neighbor-component order connectivity of a graph is equivalent to the well-known parameter domination number of the graph. The problem of computing the domination number of an arbitrary graph is NP-hard, and computing neighbor-component order connectivity of a graph for an arbitrary threshold value is also NP-hard. Here, we present a linear-time algorithm for computing the neighbor-component order connectivity of an arbitrary tree for an arbitrary threshold value, thus generalizing the classic linear algorithm of Cockayne, Goodman, and Hedetniemi for the domination number of the tree. <\/jats:p>","DOI":"10.1142\/s179383092250183x","type":"journal-article","created":{"date-parts":[[2022,11,16]],"date-time":"2022-11-16T11:34:37Z","timestamp":1668598477000},"source":"Crossref","is-referenced-by-count":1,"title":["A linear algorithm for the neighbor-component order connectivity of arbitrary trees"],"prefix":"10.1142","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0742-1011","authenticated-orcid":false,"given":"Kristi","family":"Luttrell","sequence":"first","affiliation":[{"name":"Mathematics Department, Seton Hall University, 400 South Orange Avenue, South Orange, NJ 07926, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,12,22]]},"reference":[{"key":"S179383092250183XBIB001","first-page":"109","volume-title":"Graph Theory, Combinatorics, Algorithms, and Applications","author":"Boesch F.","year":"1998"},{"key":"S179383092250183XBIB002","first-page":"145","volume":"131","author":"Boesch F.","year":"1998","journal-title":"Congr.
