hop of those help? You can always add specific LaTeX (or HTML) attributes to the result of a source block:
code :
#+BEGIN_SRC dot :file hallo1_1_1.png 
 digraph hallo1_1_1 {
  A [shape = "circle",style=filled, fillcolor=yellow];
  }
#+END_SRC

#+attr_latex: :width 2cm
#+RESULTS:
[[file:hallo1_1_1.png]]

it should still fix some issue Step one: eliminate all cycles. You can find a cycle by picking any node and doing a DFS from there. If you don't find a cycle find another node that you haven't visisted in the previous DFS and do a DFS from that node. If you find a cycle collapse all the nodes into a single one. Basically if you reach any of the nodes in the cycle, you will go through the cycle to get all the weights. Since you can reuse nodes and edges you will always be able to continue on your path as before. After you found a cycle repeat the algorithm, until you have collapsed all cycles.
Step two: find a path through the collapsed graph. Now there are no cycles, so you can use Bellman Ford and find the longest route (you need to change the conditions to look for longer paths instead of shorter). Because every collapsed node has the weigth of the cycle it represents you get the weight you are looking for. If you want to reconstruct the path then you also need to look at the cycles you collapsed and expand them in place, taking care to add the path from the input point to the exit point in the cycle (Say you have a cycle with 10 nodes, the input edge goes to node 1 but the exit edge goes from node 5, so you need to add the entire cycle 1,2,3,4,5.. 10 starting from the input edge and then add the part of the cycle that takes you to the exit edge, in this case 1,2,3,4,5).
