Résumé

Given two trees (a target $T$ and a pattern $P$ ) and a natural number $w$ , window embedded subtree problems consist in deciding whether $P$ occurs as an embedded subtree of $T$ and/or finding the number of size (at most) $w$ windows of $T$ which contain pattern $P$ as an embedded subtree. $P$ is an embedded subtree of $T$ if $P$ can be obtained by deleting some nodes from $T$ (if a node $v$ is deleted, all edges adjacent to $v$ are also deleted, and outgoing edges are replaced by edges going from the parent of $v$ (if it exists) to the children of $v$ ). Deciding whether $P$ is an embedded subtree of $T$ is known to be NP-complete. Our algorithms run in time $O (| T | 2^{2^{| P |}})$ where $| T |$ (resp. $| P |$ ) is the size of $T$ (resp. $P$ ).
