The Complexity of Plan Existence and Evaluation in Probabilistic Domains

چکیده
We examine the computational complexity of testing and finding small plans in prob abilistic planning domains with succinct rep resentations. We find that many problems of interest are complete for a variety of com plexity classes: NP, co-NP, PP, NPPP, co NPPP, and PSPACE. Of these, the proba bilistic classes PP and NPPP are likely to be of special interest in the field of uncer tainty in artificial intelligence and are deserv ing of additional study. These results suggest a fruitful direction of future algorithmic de velopment.

The Computational Complexity of Probabilistic Planning
We examine the computational complexity of testing and nding small plans in probabilistic planning domains with both at and propositional representations. The complexity of plan evaluation and existence varies with the plan type sought; we examine totally ordered plans, acyclic plans, and looping plans, and partially ordered plans under three natural de nitions of plan value. We show that probl...

متن کاملExtension of Cube Attack with Probabilistic Equations and its Application on Cryptanalysis of KATAN Cipher
Cube Attack is a successful case of Algebraic Attack. Cube Attack consists of two phases, linear equation extraction and solving the extracted equation system. Due to the high complexity of equation extraction phase in finding linear equations, we can extract nonlinear ones that could be approximated to linear equations with high probability. The probabilistic equations could be considered as l...

متن کاملTorsion Effect on the RC Structures using Fragility Curves Concerning Soil-Structure Interaction
The existence of torsion, as well as consideration of the Soil-Structure Interaction (SSI), increase the natural periods of the structure resulting from a subsequent decrease in the seismic demand of the system. This paper summarizes the probabilistic assessment for evaluation of collapse fragility curves in concrete moment resisting structure with different mass center eccentricities. A 12-sto...
