We study a dynamic scenario of the static route planning problem in road networks. Particularly, we put accent on the most practical dynamic case – increased edge weights (up to infinity). We show how to enhance the scope-based route planning approach presented at ESA’11, [16] to intuitively by-pass closures by detours. Three variants of a detour “admissibility” are presented – from a simple on...

Let G be a plane graph where each edge is a line segment. We consider the problem of computing the maximum detour of G, defined as the maximum over all pairs of distinct points p and q of G of the ratio between the distance between p and q in G and the Euclidean distance ‖pq‖. The fastest known algorithm for this problem has Θ(n2) running time where n is the number of vertices. We show how to o...

This study explored the experience of occupational therapists who encountered counterproductive events during their fieldwork training. Interviews were conducted to gather information regarding the participant's perception of factors that contributed to a negative fieldwork experience. The results were divided into major categories: (1) the role of the supervisor, (2) poor supervisory character...

Objectives: To find the connected restrained detour number for standard graphs and mesh graphs. Methods: By determining set with minimum cardinality, of a graph is investigated. Findings: We study that altered when we add pendent vertices. The maximum degree vertices are deleted computed. Novelty: Finding path plays vital role in network-based systems. Planning largest route essential business,...
