Portably Solving File TOCTTOU Races with Hardness Amplification
The file-system API of contemporary systems makes programs vulnerable to TOCTTOU (time of check to time of use) race conditions. Existing solutions either help users to detect the...

Pure Nash equilibria: complete characterization of hard and easy graphical games
We consider the computational complexity of pure Nash equilibria in graphical games. It is known that the problem is NP-complete in general, but tractable (i.e., in P) for special...

Multi-attribute Decision Making in a Complex Multiagent Environment Using Reinforcement Learning with Selective Perception
Abstract. Choosing between multiple alternative tasks is a hard problem for agents evolving in an uncertain real-time multiagent environment. An example of such environment is the ...

Hiding Satisfying Assignments: Two Are Better than One
The evaluation of incomplete satisfiability solvers depends critically on the availability of hard satisfiable instances. A plausible source of such instances consists of random k...

Brute-Force Determination of Multiprocessor Schedulability for Sets of Sporadic Hard-Deadline Tasks
This report describes a necessary and sufficient test for the schedulability of a set of sporadic harddeadline tasks on a multiprocessor platform, using any of a variety of schedu...
