algorithm - C programming language, shortest path -

-

i'm writing code find shortest distance between 2 points. code working perfect till now. mean finds distance , path should pass. need print information, should make print function. way works that: example initial point 4 , final 13.

i should come algorithm check intermediate points. let's between 4 & 13 there point : 7

4--7--13 need check every point between them like:

4--6--7--9--13 more specific check if there point between 4-6 , 6-7 , 7-9 , 9-13. next in next iteration may formed list like:

4--2--6--7--5--9--17--13 let's there not intermediate value between them. , should print. appreciate help, suggestion may give me

the warshall-floyd algorithm (used op), has version able determine path in addition distance between nodes of graph:

floyd-warshall algorithm path-reconstruction

however, must noted not best possible algorithm solve shortest-path problem.

c++ - Troubles when compiling phash program -

-
here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
