Relaxed meaning I dropped some constraints.   I can send you the whole model and data if you want.   Changed value of parameter MIPGap to 0.05Prev: 0.0001 Min: 0.0 Max: inf Default: 0.0001Changed v...

I also just ran this with a reduced mip gap to 0.01%, which gives the tighter upper bound of about 2.65 Optimal solution found (tolerance 1.00e-03)Best objective 2.649999711392e+00, best bound 2.65...

Here is the log data from the relaxed version of the problem.  I have the best feasible solution I have for the original problem fed into this relaxed version as a MIP start.   Gurobi Optimizer ver...

The problem is phrased as a maximization.   Thus, by "dual bound", I mean an upper bound on the problem.   This is why I used MIPFocus 2 and 3. The solution to the relaxed version of the problem is...

Is there a simple way to load the solution file as an initial starting solution for resolving the MIP later? For instance, if on one run I solve and store the solution model.write('model.sol') can ...
