active constraint meaning in English

活动约束
起作用的约束
有效约束

This method searched along the edge of active constraints in quadratic programming , which would obtain available solution anytime in calculation and get the optimal solution more quickly
该算法使用等式约束二次规划变更指标沿积极约束边界搜索，可在计算中任何时候得到可行解，并较快得到最优解。
The algorithms do not use any pivotal operation , but use the generalized ( e , d ) - active constraint set to determine the generalized projection matrices . the diagonal matrix of the projection matrix is a new construction method and it is the main function to insure the finite termination
算法不使用任何转轴运算，仅用( ， ) ?积极约束集确定广义投影阵，该投影阵中的对角阵是一种新的构造方法，它在保证算法的有限步收敛中起十分重要的作用。
