MODAM-11: Extend the surplus maximization solver for the additional bid types

[gokhanceyhan]

In the first phase, add the quadratic objective function, flexible bids and the linked block bids.

[gokhanceyhan]

New bid types integrated:

• piece-wise hourly bids (P)
• profile block bids (PB)
• linked block bids and mutually exclusive block bids
• flexible (F) and profile flexible (PF) bids that can span multiple periods

Remaning work:

• add block bid constraints for benders cplex + scip
• update gcuts for cplex + scip
• update solution creator for cplex + scip at the end of the solving process
• scip miqp solution is problematic
• primal-dual model needs to be updated for the no-prb model

In the mean-time, only the Gurobi solver should be used to solve the instances with piece-wise hourly bids, linked block bids, mutually exclusive block bids and flexible bids. Both primal-dual and Benders decomposition algorithms can be used. However, only the Benders decomposition algorithm should be used to solve the no-prb model for the instances with those bid types.

In the no-prb model, child block bids never become PRB and mutually exclusive block bids cannot become PRB if one of those is accepted similar to the acceptance of a flexible bid for one of the periods.
