Thus, a relaxation of the constraint of an integer problem does not necessarily improve the solution, because the feasible region is discrete and not continuous.
因此，整型问题的约束放松并不一定会改进解决方案，因为可行域是离散的，而不是连续的。
This mechanism includes participation constraint and incentive compatibility constraint, so it is mechanism which is feasible and enforceable.
该机制考虑了激励相容约束和参与约束，因此是一个可行和可实施的机制。
