Looking for a Version of Schaefer's Dichotomy Theorem When Each Variable Occurs at Most Twice
نویسنده
چکیده
We study the complexity of generalized satissability problem for formulas whose variables occur at most twice. We prove a dichotomy theorem for a special case of generalized satissability with constants and a suucient condition, inspired by matching theory, for its polynomial time solvability.

The Topology of Rr Lyrae Instability Strip and the Oosterhoff Dichotomy
Convective pulsating models with Y = 0:24, stellar mass M = 0:65M , 0:75M , under selected assumptions about luminosities and e ective temperatures, are used together with stellar atmosphere computations to get the predicted dependence of RR Lyrae instability strip on stellar mass in the observative plane (MV ; B V ). The comparison with observed variables belonging to the globular clusters M3 ...
متن کاملThe Complexity of Satisfiability Problems: Refining Schaefer's Theorem
Schaefer proved in 1978 that the Boolean constraint satisfaction problem for a given constraint language is either in P or is NPcomplete, and identified all tractable cases. Schaefer’s dichotomy theorem actually shows that there are at most two constraint satisfaction problems, up to polynomial-time isomorphism (and these isomorphism types are distinct if and only if P 6= NP). We show that if o...
متن کاملThe phase transition in random Horn satis
This paper studies the phase transition in random Horn satissability: under the random model (n; m) in which a formula is obtained by choosing m clauses independently, uniformly at random, and with repetition from all Horn clauses in n variables, (n) = 2 n is the satissability threshold for the Horn satissability. The threshold is coarse since, if (n) = c 2 n then lim n!1 Pr 2(n;;(n)) is satiss...

متن کاملEntanglement Transmission under Adversarially Selected Quantum Noise
We derive a regularized formula for the common randomness assisted entanglement transmission capacity of finite arbitrarily varying quantum channels (AVQC’s). For finite AVQC’s with positive capacity for classical message transmission we show, by derandomization through classical forward communication, that the random capacity for entanglement transmission equals the deterministic capacity for ...
