We study a Stackelberg variant of the classical Most Vital Links problem, modeled as a one-round adversarial game between an attacker and a defender. The attacker strategically removes up to k edges from a flow network to maximally disrupt flow between a source s and a sink t, after which the defend
We study the problem of fairly and efficiently allocating indivisible goods among agents with additive valuations. We focus on envy-freeness up to any good (EFX) — an important fairness notion in fair division of indivisible goods. A central open question in this field is whether EFX allocations alw
Time-inconsistent behavior, such as procrastination or abandonment of long-term goals, arises when agents evaluate immediate outcomes disproportionately higher than future ones. This leads to globally suboptimal behavior, where plans are frequently revised or abandoned entirely. In the influential m
There is a well-known approach to cope with NP-hard problems in practice: reduce the given problem to SAT or MAXSAT and run a SAT or a MaxSAT solver. This method is very efficient since SAT/MaxSAT solvers are extremely well-studied, as well as the complexity of these problems. At AAAI 2011, Li et al…
