Hi,  I am wondering if it is  possible to set a specific value for the best LP bound of  a  Mathematical program (before executing the Mathematical programof course)? 

Thanks

Hi @sara62. No, that is not possible. (And I do not see how that would be useful.)

Would you not be able to simulate this by just adding a new constraint before solving the MIP stating

objective >= bound_you_have_for_LP

This way you would enforce the LP relaxation value to be at least >= bound

Only real usecase I could see for this is if you have a formulation that has a bad relaxation and somehow you are able to provide more informative bounds on the initial relaxation?
