求解網(wǎng)絡(luò)中的最短路徑。假設(shè)某個計算機網(wǎng)絡(luò)有n個站點,依次編號為1,2,…,n;有的站點之間有直接的線路連接(即這兩個站點之間沒有其它站點),有的站點之間沒有直接的線路連接。如果用三元組(i,j,f)來表示該網(wǎng)絡(luò)中的站點I和站點j之間有直接的線路連接且它們之間的距離為f 當已知該網(wǎng)絡(luò)各站點之間的直接連接情況由m個三元組(i1,j1,f1),(i2,j2,f2),…,(im,jm,fm)確定時,要求計算出對于網(wǎng)絡(luò)中任意一個站點g(1≤g≤n)到其余各站點的最短距離。

The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.) I have attempted to provide copious comments in the code and hope that a knowledgeable C programmer can quickly map the approach as described in the paper to what is in the program.

Many many developers all over the net respect NASM for what i s - a widespread (thus netwide), portable (thus netwide!), very flexible and mature assembler tool with support for many output formats (thus netwide!!). Now we have good news for you: NASM is licensed under LGPL. This means its development is open to even wider society of programmers wishing to improve their lovely assembler. The NASM project is now situated at SourceForge.net, the most famous Open Source development center on The Net. Visit our development page at http://nasm.2y.net/ and our SF project at http://sf.net/projects/nasm/

提出了一種基于樣本的分級檢索 MPEG 視頻的新方法:首先用I 幀的dct_dc_size 字段快速粗檢,然后用斷層攝影(tomography)法分析B 幀運動矢 量的時空分布特性以進一步縮小結(jié)果集,最后用DC 圖像的精確匹配方法驗證檢索結(jié)果.試驗結(jié)果表明,本方法 所需計算量較小,且可保證較高的檢索精度.
