One Action Too Many: Inapproximability of Budgeted Combinatorial Contracts

Michal Feldman, Yoav Gal-Tzur, Tomasz Ponitka +1

We study multi-agent contract design with combinatorial actions, under budget constraints, and for a broad class of objective functions, including profit (principal's utility), rew…
