Hello Brady, Andrew indicated in http://lists.gnu.org/archive/html/help-glpk/2010-02/msg00206.html that he is interested in supporting branching analysis in GLPK.
A description of the BAK file format is given in http://www.rosemaryroad.org/projects/BAK/browser/trunk/grammar_details Unfortunately it is not a strict file format specification. E.g. according to your document it is unclear which of the following would be a valid format of <time>: 00:13:14.15 780 s 3.6 h The document says: "We also need to know whether each node is a left branch or right branch, indicated with a branch direction of 'L' or 'R'." It is unclear what left of right refers to. Do you mean branching down to 0 and up to 1 (as implemented in patched glpios03.c) - or the output sequence in the diagrams? Hence I think the next step for moving BAK file support to GLPK should be to create an unambiguous file format specification.
