This library provides efficient methods to enumerate all elements of a set in order of the population count, or the ordered enumerations of the elements of the powerset of a set. First, the empty set, then all 1-element sets, all 2-element sets, etc. Such enumerations are important for algorithms over unordered data sets. Examples include the travelling salesman problem and the closely related Hamiltonian path problem.

Readme for OrderedBits-

Build Status


The OrderedBits library provides methods to generate unboxed vectors of Ints (and others) ordered by their population count or Hamming distance to the 0 set. In other words, we enumerate the power set of a given input set.

Such an order is important for dynamic programming algorithms for Hamiltonian path problems and the travelling salesman problem.
