v0.9.2
9fa4a1f

v0.9.2 improves the performance with faster and better UE convergency along with several bug fixes.

  1. Optimize the column generation module per TransOMS, which slightly reduces the running time and greatly improves the UE convergency by three times. For the Chicago Sketch Network, the UE gaps are 0.091% (or 13789.25) and 0.0326% (or 4909.65).
  2. Fix the bug in updating the total system travel time in _update_column_gradient_cost_and_flow(), which shall be updated before shifting flow.
  3. Fix the potential issue in path engine where the last through node may be traversed.
  4. Fix the bug in load_columns() that node path and link path shall be reversed in the loading process (#31).
  5. Add documentation on conducting simulation by directly loading existing UE result from agent.csv (#31).
