Given an edge weighted tree T(V, E), rooted at a designated base vertex \(r \in V\), and a color from a set of colors \(C=\{1,\ldots ,k\}\) assigned to every vertex \(v \in V\), All Colors Shortest Path problem on trees (ACSP-t) seeks the shortest, possibly non-simple, path starting from r in T such that at least one node from every distinct color...

Redundant stops of elevators result in an unnecessary consumption of energy and time. Moreover, redundant stops increase waiting time, leading to problems such physical and psychological discomfort for passengers inside the car as well as those waiting outside. This paper proposes a real- time elevator monitoring system to reduce total travelli...
