equality constraint
1.To the inequality constrained least squares adjustment problem, this paper converts many inequality constraints into one equality constraint by using aggregate function of non-linear programming; a basic augmented Lagrangean algorithm can obtain the solutions for equality constrained non-linear programming problem and the solutions are identical to those obtained by the Bayesian method and/or simplex algorithm.
2.Admissibility of linear prediction in linear model with linear equality constraint under quadratic loss function are investigated. Necessary and sufficient conditions for a linear prediction Ly s(Ly s+a) of conditional linear predictable variable Qy to be admissible are obtained.
3.After introspecting on the dilemma in the social mobility of farmers, Kunshan City breaks down cultural constraint, discards psychological estrangement, establishes equality, applies three reorientations to farmers and carries out three synchronizations between farmers and natives in the policy and therefore, improves both the healthy development of urbanization and building of an harmonious society.
