Hi Dave,<br>
<br>
I'm not sure the Daniel used the example data network for this example. The data looks like one of the matrix I used in my test cases.<br>
<br>
src/tsp/test/*.test<br>
<br>
I just made up numbers for a symmetric matrix. It was not taken from an actual network.<br>
<br>
So the sly part is that its NOT from a graph ;)<br>
<br>
Daniel - please correct me it you did something else.<br>

In the travel sales person problem an example is provided, I having<br>
problems understanding it<br>
<br>
The example route network is posted as<br>
<a href="http://docs.pgrouting.org/dev/doc/src/developer/sampledata.html#sampledata" target="_blank">http://docs.pgrouting.org/dev/<u></u>doc/src/developer/sampledata.<u></u>html#sampledata</a><br>
<br>
I have assume the distance between red node 1 and red node 3 is 2, ie<br>
the unit distance 1 +1 which I make to be 2<br>
<br>
given that<br>
<br>
I think the route matrix should be<br>
<br>
1 2 3 4<br>
======<br>
1 | 0 1 2 3<br>
2 | 1 0 1 2<br>
3 | 2 1 0 1<br>
4 | 3 2 1 0<br>
<br>
distance 1 to 4 is 1+1 +1 ==3<br>
distance 2 to 4 is 1+1 ==2<br>
distance 3 to 4 is 1<br>
etc<br>
<br>
But the give value is (please see<br>
<a href="http://docs.pgrouting.org/dev/src/tsp/doc/index.html" target="_blank">http://docs.pgrouting.org/dev/<u></u>src/tsp/doc/index.html</a>)<br>
1 2 3 4<br>
<br>
1 {0,1,2,3},<br>
2 {1,0,3,2},<br>
3 {2,3,0,4},<br>
4 {3,2,4,0}<br>
<br>
I just don't understand how the distance between 3 and 4 can be the<br>
value 4, ditto he values between 2 and 3<br>
<br>
Have I missed something sly ?<br>
<br>
Dave.<br>
