unit commitment constraint 机组启停约束
To refine your unit test further, you can assert that the validation failed for a specific constraint on a specific field, as shown in Listing 8.
要进一步细化单元测试，您可以断言验证会因为特定字段上的特定约束而失败，如清单8所示。
Therefore, a relaxation of one unit in that constraint (an increment of one hour) would make the objective function's optimal value become better by the marginal value 1 and become 181.
因此，这个约束中放松一个单位（增加一个小时）可以使目标函数的优化值增加边界值 1，成为 181。
Analogously, if we could relax the sugar constraint by one unit, the objective function would improve by 0.075.
类似地，如果我们将糖约束放松一个单位，那么目标函数就会改进0.075。
