Solving SCS for bounded length strings in fewer than 2n steps
It is still not known whether a shortest common superstring (SCS) of n input strings can be found faster than in O∗(2n) time (O∗(·) suppresses polynomial factors of the input length). In this short note, we show that for any constant r, SCS for strings of length at most r can be solved in time O∗(2(1−c(r))n) where c(r) = (1 + 2r2)−1. For this, we introduce so-called hierarchical graphs that all...
متن کاملSolving Incremental Satisfiability
Propositional satisfiability (SAT) problem is fundamental to the theory of NPcompleteness. Indeed, using the concept of ”polynomial-time reducibility” all NPcomplete problems can be polynomially reduced to SAT. Thus, any new technique for satisfiability problems will lead to general approaches for thousands of hard combinatorial problems. In this paper, we introduce the incremental propositiona...
متن کاملSecond Preimages on n-Bit Hash Functions for Much Less than 2n Work
We provide a second preimage attack on all n-bit iterated hash functions with Damgard-Merkle strengthening and n-bit intermediate states, allowing a second preimage to be found for a 2-messageblock message with about k× 2 + 2n−k+1 work. Using SHA1 as an example, our attack can find a second preimage for a 2 byte message in 2 work, rather than the previously expected 2 work. We also provide slig...
متن کاملSolving satisfiability using inclusion-exclusion
Using Maple, we implement a SAT solver based on the principle of inclusion-exclusion and the Bonferroni inequalities. Using randomly generated input, we investigate the performance of our solver as a function of the number of variables and number of clauses. We also test it against Maple’s built-in tautology procedure. Finally, we implement the Lovász local lemma with Maple and discuss its appl...
متن کاملSolving the incremental satisfiability problem
Given a set of clauses in propositional logic that have been found satis able we wish to check whether satis ability is preserved when the clause set is incremented with a new clause We describe an e cient implementation of the Davis Putnam Loveland algorithm for checking satis ability of the original set We then show how to modify the algorithm for e cient solution of the incremental problem w...
