Sentence examples for median problem is from inspiring English sources

In this paper, a tri-level defense facility location model for full coverage in r-interdiction median problem is addressed which considers both modeling approaches, simultaneously.

The hub median problem is to locate hub facilities in a network and to allocate non-hub nodes to hub nodes such that the total transportation cost is minimized.

The Budget Constrained Connected Median Problem is the following: We are given an undirected graph G= V,E) with two different edge-weight functions c (modeling the construction or communication cost) and d (modeling the service distance), and a bound B on the total service distance.

The median problem is known to be NP-hard [ 6] under most rearrangement distances proposed so far.

The rearrangement median problem is to find a genome M such that d(P, M + d(Q, M + d(R, M) is minimal.
