A Cryptanalysis of the Double-Round Quadratic Cryptosystem
In the 80’s Matsumoto and Imai [8] proposed public key cryptosystems based on the difficulty of solving systems of polynomials in several variables. Although these first schemes...

Complexity of Earliest Query Answering with Streaming Tree Automata
We investigate the complexity of earliest query answering for n-ary node selection queries defined by streaming tree automata (STAs). We elaborate an algorithm that selects query ...

CORL: A Continuous-state Offset-dynamics Reinforcement Learner
Continuous state spaces and stochastic, switching dynamics characterize a number of rich, realworld domains, such as robot navigation across varying terrain. We describe a reinfor...

Forward-Chaining Planning in Nondeterministic Domains
In this paper, we present a general technique for taking forward-chaining planners for deterministic domains (e.g., HSP, TLPlan, TALplanner, and SHOP2) and adapting them to work i...
