深入研究交错非均匀网格的差分方案的构造与实施，基于交错网格提出了有效离散格式；采用simple算法对速度压力关系解耦，列举几种代数方程的求解办法，分析并阐述了逐线松弛技术。 - A branch and bound algorithm for solving a class of nonlinear 0 - 1 knapsack problems is proposed , in which branching is common 0 - 1 variables one and a better feasible solution is found by a simply integer heuristic method as well as a lower bound of the optimal value of the subproblem in the each branching node is determined by solving linear programming relaxed approximate problem to be obtained with linear relaxed technique
摘要构造出了一类可分离非线性0 - 1背包问题的分枝定界算法，分枝的过程是普通的0 - 1变量分枝，用简单的取整启发式法确定更好的可行解；而在每个分枝结点处用线性松弛技术确定了它的子问题的一个线性规划松弛逼近，由此得到最优值的一个下界。
