  2. Computers and Intractability - Wikipedia

    Soon after it appeared, the book received positive reviews by reputed researchers in the area of theoretical computer science. In his review, Ronald V. Book recommends the book to "anyone who wishes to learn about the subject of NP-completeness", and he explicitly mentions the "extremely useful" appendix with over 300 NP-hard computational problems.

  3. Weak NP-completeness - Wikipedia

    en.wikipedia.org/wiki/Weak_NP-completeness

    An example is the partition problem. Both weak NP-hardness and weak polynomial-time correspond to encoding the input agents in binary coding. If a problem is strongly NP-hard, then it does not even have a pseudo-polynomial time algorithm. It also does not have a fully-polynomial time approximation scheme. An example is the 3-partition problem.

  4. Bin packing problem - Wikipedia

    en.wikipedia.org/wiki/Bin_packing_problem

    Computationally, the problem is NP-hard, and the corresponding decision problem, deciding if items can fit into a specified number of bins, is NP-complete. Despite its worst-case hardness, optimal solutions to very large instances of the problem can be produced with sophisticated algorithms. In addition, many approximation algorithms exist.

  5. P versus NP problem - Wikipedia

    en.wikipedia.org/wiki/P_versus_NP_problem

    Informally, an NP-complete problem is an NP problem that is at least as "tough" as any other problem in NP. NP-hard problems are those at least as hard as NP problems; i.e., all NP problems can be reduced (in polynomial time) to them. NP-hard problems need not be in NP; i.e., they need not have solutions verifiable in polynomial time.

  7. Partition problem - Wikipedia

    en.wikipedia.org/wiki/Partition_problem

    Since the problem is NP-hard, such algorithms might take exponential time in general, but may be practically usable in certain cases. Algorithms developed for multiway number partitioning include: The pseudopolynomial time number partitioning takes O ( n m ) {\textstyle O(nm)} memory, where m is the largest number in the input.

  9. NP-hardness - Wikipedia

    en.wikipedia.org/wiki/NP-hardness

    As it is suspected, but unproven, that P≠NP, it is unlikely that any polynomial-time algorithms for NP-hard problems exist. [3] [4] A simple example of an NP-hard problem is the subset sum problem. Informally, if H is NP-hard, then it is at least as difficult to solve as the problems in NP.
