This article examines the geographical corridors for the establishment of rice in seventeenth-century Dutch Guiana. One corridor of introduction is associated with the expulsion of Dutch planters from Brazil in 1644, whose slaves reestablished longstanding subsistence preferences with their exodus to the colony. Another corridor links its introduction to the African Gold Coast, where rice devel...

An (N ;n,m, {w1, . . . , wt})-separating hash family is a set H of N functions h : X −→ Y with |X| = n, |Y | = m, t ≥ 2 having the following property. For any pairwise disjoint subsets C1, . . . , Ct ⊆ X with |Ci| = wi, i = 1, . . . , t, there exists at least one function h ∈ H such that h(C1), h(C2), . . . , h(Ct) are pairwise disjoint. Separating hash families generalize many known combinator...

This paper studies action-based reinforcement learning in finite perfectinformation games. Restrictions on the valuation updating rule that that are necessary and sufficient for the play to converge to a subgame-perfect Nash equilibrium (SPNE) are identified. These conditions encompass well-known examples of reinforcement learning and are mild enough to contain other interesting and plausible l...

In generic perfect-information games the unique Subgame-Perfect Equilibrium (SPE) outcome is identical to the one predicted by several rationalizability notions, like Extensive-Form Rationalizability (EFR), the Backward Dominance Procedure (BDP), and Extensive-Form Rationalizability of the Agent form (AEFR). We show that, in contrast, within the general class of perfect information games all th...

The theory of graph games is the foundation for modeling and synthesizing reactive processes. In the synthesis of stochastic processes, we use 2 2 -player games where some transitions of the game graph are controlled by two adversarial players, the System and the Environment, and the other transitions are determined probabilistically. We consider 212 -player games where the objective of the Sys...
