The Travelling Salesmen Problem (TSP) is one of the most important and famous combinational optimization problems that aim to find the shortest tour. In this problem, the salesman starts to move from an arbitrary place called depot and after visiting all nodes, finally comes back to depot. Solving this problem seems hard because program statement is simple and leads this problem belonging to NP...

We study fairness in house allocation, where $m$ houses are to be allocated among $n$ agents so that every agent receives one house. show maximizing the number of envy-free is hard approximate within a factor $n^{1-\gamma}$ for any constant $\gamma>0$, and exact version NP-hard even binary utilities. Moreover, we prove deciding whether proportional allocation exists computationally hard, wherea...

Abstract In this article, we propose a framework to tackle conflict prevention, an issue which has received interest in several policy areas. A key challenge of forecasting for prevention is that outbreaks previously peaceful countries are rare events and therefore hard predict. To make progress problem, project summarizes more than four million newspaper articles using topic model. The topics ...

Abstract Wilfrid Sellars’ denunciation of the Myth Given was meant to clarify, against empiricism, that perceptual episodes alone are insufficient ground and justify knowledge. Sellars showed in order accomplish such epistemic tasks, more resources capacities, as those involved using concepts, needed. Perceptual knowledge belongs space reasons not an independent realm experience. Dan Hutto Eric...

Students often do not understand the difference between collaboration and compromise. Collaboration, also known as problem solving, an integrative solution, or a win-win solution is, ‘‘a strategy that involves seeking a mutually satisfactory alternative’’ (Pruitt & Kim, 2004, p. 297). Compromise, in contrast, is ‘‘an obvious alternative that stands partway between the disputants’ preferred posi...
