The brain is able to flexibly select behaviors that adapt to both its environment and its present goals. This cognitive control is understood to occur within the hierarchy of the cortex and relies strongly on the prefrontal and premotor cortices, whi

A Euclidean skeleton is a set of edges in the interior (or on the boundary) of a polygon that intersects any line segment that joins two points outside of the polygon and that intersects the polygon. In this paper we study minimum cardinality Euclide

We present methods for simplifying the geometry of polygonal obstacles as a preprocessing step to solving obstacle-avoiding Steiner network problems in the plane. The methods reduce the total number of vertices and edges that need to be considered fo

Consider a configuration of points comprising a point q and a set of concyclic points R that are all a given distance r from q in the Euclidean plane. In this paper, we investigate the relationship between the length of a minimum Steiner tree (MStT)

The geometric 2-connected Steiner network problem asks for a shortest bridgeless network spanning a given set of terminals in the plane such that the total length of all edges of the network, as measured in the l p metric, is a minimum. Using reducti

The prize-collecting Euclidean Steiner tree (PCEST) problem is a generalization of the well-known Euclidean Steiner tree (EST) problem. All points given in an EST problem instance are connected by the shortest possible network in a solution. A soluti

We introduce the concept of an obstacle skeleton, which is a set of line segments inside a polygonal obstacle $$\omega $$ that can be used in place of $$\omega $$ when performing intersection tests for obstacle-avoiding network problems in the plane.

Relay node placement, which aims to connect pre-deployed sensor nodes to base stations, is essential in minimizing the costs of wireless sensor networks. In this paper, we formulate the new Node-Weighted Partial Terminal Steiner Tree Problem (NWPTSTP

Open-pit mines are surface excavations created to extract valuable material which, in most cases, is located near the surface. Pushbacks are connected regions of a mine with enough working area to support the mining operation over a defined period. P

A fundamental goal of neuroscience is to understand how cognitive processes, such as operant conditioning, are performed by the brain. Typical and well studied examples of operant conditioning, in which the firing rates of individual cortical neurons
