      Several improvements to random_rewire() / random_graph() · 8240714e
      Tiago Peixoto authored
      This introduces several simplifications and corrections to the graph
      rewire algorithm, to guarantee unbiased sampling.
      
      Now a move is outright rejected if it produces a
      self-loop/parallel-edge, instead of retried. This also adds a
      "non-sweep" mode, where edges are rewired randomly, possibly with
      repetition.
      
      The edge moves are now simplified to the target of the edges only,
      since swaping sources is redundant.
      
      The number of iterations can now be explicitly modified, so it is not
      necessary to call the function more than once, and it is emphasized in
      the documentation that only after sufficiently many iterations can the
      graph be guaranteed to be fully mixed.

      Improve price_network() seeding semantics · c11b6af7
      Tiago Peixoto authored
      Now, if 'm' is larger than the seed graph, it is set to the size of the
      seed graph, and is increased progressively until it matches the desired
      value. This removes the need to start with a random seed graph of the
      appropriate size.
      
      This also includes modifications which make the code more robust
      against parameter choices which don't make much sense, e.g. lead to
      negative probabilites.

      Refactor random_graph() · 1f28345e
      Tiago Peixoto authored
      Now the degree sequence is verified with Erdös-Gallai inequalities, and
      the edges are connected in a deterministic fashion. The edges then are
      rewired with the random_rewire() function.

      Refactor random_rewire() · b678e65a
      Tiago Peixoto authored
      This extensively modifies the random_rewire() algorithm, so that only
      either the source or the edge of each edge is rewired (not both, as
      previously), and no parallel edges are created during the algorithm (if
      desired).
      
      The new version is much faster, and never gets stuck. However, more than
      one run may be necessary in order to obtain a uniform shuffling.

      Fix rewiring bias bug for undirected graphs · d158af8f
      Tiago Peixoto authored
      This fixes a problem, where the underlying edge directionality would
      cause correlations to arise when rewiring undirected graphs. Now each
      edge is correctly considered in both possible orientations, which are
      chosen randomly.

      Relax boost version requirements · 154ef865
      Tiago Peixoto authored
      This allows compilation with older versions of boost (>=1.38), which in
      some sistems are the only option. This commit also removes the linking
      of the boost_graph shared library, since none of its symbols are
      actually required.
