EIFEL—A New Approach for Digital Education RNA secondary structure, has to be found in a sequence. We show that the . . . 2-. . problem is .-complete for structured patterns where no pair precedes the other, but can be solved in polynomial time for several interesting special cases.彻底明白 发表于 2025-3-30 15:58:08

We show that some of the most obvious instances of this framework lead to NP-hard optimization problems and are not approximable within any constant factor. We also givNORM 发表于 2025-3-31 10:55:51
Smart Innovation, Systems and Technologiesur algorithms require only . bits (.(./ log .) words) where . is the total length of the strings. We propose three algorithms for different inputs: When the input is only the strings, their compressed suffix array, or their compressed suffix tree. Their time complexities are .(. log .), .(. log. .)inscribe 发表于 2025-3-31 16:48:34

We prove that this problem is solved in polynomial time if the size of a PSSM is bounded by a constant. On the other hand, we prove that this problem is NP-hard if the摇晃 发表于 2025-3-31 23:03:33
