comment Routing and OpenLayers: How would you connect a point to another through a 'road' node?
Could you explain why you want to write the algorithms yourself if the problem of routing has already been solved multiple times before? If you want to write it yourself, which programming language do you want to use? Of course I can reopen your question but I doubt that the current problem description is enough to provide the answer you're looking for. One issue I have: first you talk about pgRouting, then you say that you're not asking for a whole routing package ... Try to rewrite to focus exactly on what you want to achieve.

Do you want to compute a route from A to be? Then you need routing software. If not, then I'm afraid I don't understand the question as it's currently written.
