n is the number of items, and m is the number of knapsack constraints with
capacities bj (j = 1, 2, · · ·,m). Each item xi requires aij units of resource consumption
of jth knapsack (j = 1, 2, · · ·,m) and yields ci units of profit upon inclusion.
The goal is to find a subset of items that yields maximum profit without
exceeding the resource capacities. The much simpler case with single constraint
(m = 1) is known as the single knapsack problem, which is not strongly NPhard,
and effective approximate algorithms have been developed for obtaining its
near-optimal solutions. The general case corresponding to m ≥ 2 is known as the
multidimensional knapsack problem (MKP), which is strongly NP-hard. Many
practical problems can be formulated as the MKP, for example, the capital budgeting
problem, allocating processors and databases in a distributed computer
system, and the project selection and cargo loading. Many algorithms, such as
the dynamic programming method, the enumerative method, the branch-andbound
method and the heuristic algorithms, are proposed for solving the MKP.
能不能不要这么随便啊?期待大神啊

过去两年里,我这一行里许多最优秀最聪明的人违法犯罪步入牢狱。成功的,富有的,聪明的人居然变得贪婪、咄咄逼人而且腐败。为什么?因为,和所有其他事物一样,这种情形凸显了这个所谓服务型社会的现实。我们的前辈,主要忙着生产东西,从事与生产相关的活动。现如今,我们主要忙着赚钱和与钱有关的事情。...

这就给语言的初学者在词义掌握方面造成了困难。当学习者由于自身的英语词汇量有限而不能正确表达自己的思想时,就会把类似汉语意思的英语单词生搬硬套上。例如,将“步入社会”翻译成”go to society",将“锻炼自己”表述成“practice myself”。这类错误就是学习者把其中文意思与英文意思从字面上简单地...

与“顺”相反的就是“逆”。这就是内格(指身体的内部机理与外部自然环境相适应。这句是总结自“从阴阳则生到反顺为逆”几句的。)。是故圣人不治已病治未病,不治已乱治未乱,此之谓也。所以圣人不治疗那些已经生病的人而是治疗那些还未生病的人(按现在的话说就是预防为主),不治理那些已经...
