https://doi.org/10.1007/978-981-15-2837-8 bin the colors of items must alternate. The problem has been studied extensively, but the best competitive online algorithm has competitiveness of 3. The competitiveness of 3 can be forced even when the sizes of items are ‘halved’, i.e. the sizes are restricted to be in (0, 1 / 2]. We give the firs

Cyber Situational Awareness Frontierstion and facility cost is minimized. The connection cost is proportional to the distance between each client and its assigned facility, whereas the facility cost is a nondecreasing function with respect to the total number of clients assigned to the facility. The universal facility location problem

Intelligent Devices Used in Healthcaremum of two terms, namely, the Euclidean distance between two centers and the distance of any other point to the closer center. The mixed minimax 2-center problem (.2.) is when one of the two centers is not in .. We present algorithms for solving the .2. and .2.. The time complexity of solving .2. an

https://doi.org/10.1007/978-3-031-56533-5 given a set of points inside the integer grid (in Euclidean plane) where each grid cell is .. In the MST version of the problem, the goal is to find a minimum tree that contains exactly one point from each non-empty grid cell (cluster). Similarly, in the TSP version of the problem, the goal is to f

We prove that for axis-parallel unit squares the hitting set and set cover problems are .-complete, whereas the piercing set and independent set problems are in .. For axis-parallel rectangles, we prove that the piercing set problem is .-complete, which solves an op

We show that the problem is NP-hard, even when all segments are axis-aligned. In fact, the problem is still NP-hard when we only need to cover rectangular cells of the ar
