While promoting a business or activity in geo-social networks, the geographical distance between its location and users is critical. Therefore, problem of Distance-Aware Influence Maximization (DAIM) has been investigated recently. The efficiency DAIM heavily relies on sample selection. Specifically, online seeding performance sensitive to promoted nearest location, offline precomputation numbe...

We consider a competitive facility location problem with two players. Players alternate placing points, one at a time, into the playing arena, until each of them has placed n points. The arena is then subdivided according to the nearest-neighbor rule, and the player whose points control the larger area wins. We present a winning strategy for the second player, where the arena is a circle or a l...

Relief logistics is one of the most effective tools in the crisis management. Growing number of global disasters and crisis events in Iran in the last decade indicates the importance of relief logistics planning more than before. Facility location of the resources allocation is the basic instrument in relief logistics before, in, and after each crisis. In this paper, covering radius of faciliti...

in this paper, we consider a special case of weber location problem which we call goal location problem. the weber location problem asks to find location of a point in the plane such that the sum of weighted distances between this point and n existing points is minimized. in the goal location problem each existing point pi has a relevant radius ri and it’s ideal for us to locate a new facility o...

We consider the bilevel uncapacitated facility location problem with user preferences. It is known that this model may be reformulated as a one-level location problem with some additional constraints. In this paper we introduce a new reformulation and show that this reformulation dominates three previous ones from the point of view of their linear programming relaxations and may be worse than a...
