Method: Solve::GecodeSolver#resolve

Defined in:

lib/solve/gecode_solver.rb

#resolve(options = {}) ⇒ Hash, List

Returns a hash like { “Artifact Name” => “Version”,… } unless the :sorted option is true, then it returns a list like [[“Artifact Name”, “Version],…]

Options Hash (options):

• :sorted (Boolean) —

  return the solution as a sorted list instead of a Hash

Raises:

• (Errors::NoSolutionError) —

  when the demands cannot be met for the given graph.

• (Errors::UnsortableSolutionError) —

  when the :sorted option is true and the demands have a solution, but the solution contains a cyclic dependency
