sequence pairs, backtracking constructs the optimal decision sequenceSequential couple:　　Dominance rule: if one of the Si-1 and Si1 has (PJ,WJ), the other has (PK,WK), and there is wj>=wk at the same time as PJThe generation of the sequence pairs of SiA sequence couple (PP,WW) in each generated Si1 to examine which order pairs are added to the SI① to add a sequence of w② by the dominant rule (PP,WW) whether to join SI, to examine the last sequence of

Set Description For a continuous integer from 1 to n, it can be divided into two subsets, and the number of each set are equal. For example, if n = 3, for {1, 2, 3}, it can be divided into two subsets. All their numbers are equal to: {3} and {1, 2 }, this is the only distribution (the switch set location is considered to be the same division scheme, so the total

Dynamic Planning is the abstraction of a method for changing the space for time. The key is to discover sub-problems and record their results. Then use these results to reduce the computational workload.For example, 01. /* A traveler has a backpack that can use up to M kilograms and now has n items,Their weights are W1, W2,..., Wn,Their values are P1, P2,..., Pn.If each itemOnly oneAsk the traveler to obtain the maximum total value.Input Format:M, nW1, p1W2, p2......Output Format:X*/ The maximum

between 1~10, in theory 1-10 the probability that each number appears is 10%, But in fact I found that the probability of 1 and 10 appearing is about half the probability of other numbers appearing! So it's not fair to use Math.random () to generate random numbers of lottery programs. for (var i = 0; i ) { ~functio

Problemconsider a function which, for a given whole number N, returns the number of ones required when writing out all numbers between 0 and N. for example, F (13) = 6. notice that F (1) = 1. what is the next largest N such that F (n) = n? Algorithm idea: calculate the number of 1
