than W. from all such subsets, pick the maximum value subset. 1) Optimal Substructure:To consider all subsets of items, there can be two cases for every item: (1) the item is encoded in the optimal subset, (2) not supported ded in the optimal set.Therefore, the maximum value that can be obtained from n items is max of following two values.1) Maximum value obtained by n-1 items and W weight (excluding nth item ).2) Value of nth item plus maximum value obtained by n-1 items and W minus weight of

, then cap>=2 can accommodate item1, this time the value of the backpack inside the item1. Value=1, get the following array 0 1 2 3 4 5 6 7 8 9 10 11 12 0 0 1 1 1 1 1 1 1 1 1 1 1 Next deal with items 1 and a subset of 2, item2 size of 3, then only cap=3 to accommodate the ite

The built-in append () function appends an item to slice. If the slice also has free capacity (Cap (s) > len (s)), it is appended directly. Otherwise, the slice is expanded before being appended. These are detailed in the documentation for the Append () function, but the document does not say how the expansion is done, so the following is an experiment with a piece of code: Package Main func main () { s: = []int{}; println (

The topic probably said that there is a simple graph of n-point M-side, each side can only allow a certain amount of goods through. To allow the X-Bear to deliver goods from 1 to n, each bear is transported and transported in the same weight, asking for the maximum value of the weight.The two-part weight judgment is established.If the weight is known, then how many bears can be found on each side, that is, the capacity of the side divided by the weight. And judging whether the X-Bear can go to 1

Author: gnuhpcSource: http://www.cnblogs.com/gnuhpc/ 1. Background: The Intelligent Network idea originated in the United States in the middle of 1980s. The high-tech communication network environment created by the development of science and technology: the exchange and transmission system, the No. 7 signaling system, and the rapid development of the database system support the idea of business processing and switch separation. The transformation from the infrastructure of telephone networks

, the main problem with the application of the QAM modulation technology to the ADSL access technology is how to adapt to the large performance differences between different telephone lines. To achieve ideal performance, the QAM receiver needs an input signal with the same spectrum and characteristics as the sending end for decoding, the QAM receiver uses an adaptive balancer to compensate for the distortion produced by the signal during transmission. Therefore, the complexity of the ADSL system

-length sequence in which the elements are of the same type. A multidimensional array can be created simply by using its own array of elements. The elements of the array are indexed using the action symbol [], and the index starts at 0 and ends with Len (array)-1. Arrays are created using the following syntax: [Length] Type N Type{value1, value2, ..., Valuen} [...] Type{value1, value2, ..., Valuen} If you use the ...
