Gnimbus

[maihoangbichtram]

• Add route gnimbus for Gnimbus method (iterate, intermediate, solution-vote, ...).

• Add route gmethod for general group methods (save-request) : In case in the future, there is another group method implemented.

• New table GSolutionArchive which is quite similar to SolutionArchive table. Differences:

  1. column new for newly generated solutions (which have to be voted to choose a current solution).
  2. column decision_variables saves data as json to work with problems with tensor variables.

• In parse_list_to_mathjson of problem schema, if the first element is already 'List', parsing is not necessary anymore. In db_init, when saving problems to db, parse_list_to_mathjson has been run so the tensor constants are saved as mathjson in db. When problem is fetched from db, it tries to run parse_list_to_mathjson again.

• In gurobi, when there are no solutions, it will throw errors when trying to get vars and constraints from model so if there is no solutions, just simply return empty dict.
