I don't want to get technical (well actually I do), but that is not a tree and neither is the Civ 5 tech "tree". This is a DAG - Directed Acyclic Graph. Directed because the connections have direction - they are one way. Acyclic because there are no cycles - loops. And Graph because well it's a graph. Every tree is a DAG, but not all DAGs are trees. This is not a tree because some vertices have more than one parent - some technologies have more than one requirement.
This is a tree.

To be technically correct (which is the best kind of correct, obviously :-) ) not all trees are directed, so your statement "Every tree is a DAG" is not true :-)

Hi ! I just discovered your job, it's very nice and useful... Thanks !

Yeah, I misspoke. What I should have said is that every tree can be made into a DAG by just assigning some direction to each edge. And since for these types of technological progressions the requirements are always one way (directed), any tree that you would use would be directed and therefore a DAG.

P.S. I looked trough all my posts out of boredom and saw this and decided to reply even though one year has passed.

Hello!

Geed the great job!

Update it to 0.13!

Updated for 0.13. I went with a more Civ2 style this time.

Have you considered making the same for production? Starting with coal, wood and ores at the top and then going down the list of items and buildings you can build from that?

I cannot repeat how useful this is.

Little suggestion: Add prototype-name anywhere (a bit hidden), so that someone can copy/paste the tech-names directly from here.

Very nice job on your tech tree, it's quite useful.
I'd like to make 2 suggestions:
- Add a checkbox that makes cost calculations assume you have productivity III modules into everything
- Add a line at the beginning for the stuff that doesn't need to be researched, so we can know the cost of red science, mining drill, yellow belts and other basic items.

Nice!

I wonder if you could visualize the tech tree on a (invisible) cylinder. All techs would be on the surface but prerequisites can go trough the cylinder.

* The output should be optimized to have less lines going (deep) through the cylinder.
* Techs should probably be grouped by type (weapons, mining, fluids, bots? each would get a 90° arc around the cylinder)
* Techs in the back should be visible but ghosted or dimmed or something to make the front more visible.
* The dragging with the mouse should rotate the cylinder brining other things to the front.

Just some late night thoughts.

I noticed that some prerequisites seem to be missing in the 16.7 version of the tech tree. Case in point is the Logistic System. It requires the production and high tech science packs in order for the research to happen. The associated Advanced electronics 2 for the High tech science pack and the Advanced material processing 2 for the production science pack nodes are not included in the prerequisites for the logistic system node though. Mainly wanted to make it known so that if someone is depending upon the tree, they will know there might be some extra tech in there that is needed.

Were you personally confused by this?

The drawback is that clicking on Advanced Electronics gives you a line to every blue tech, and Advanced Electronics 2 gives you a line to every yellow tech.

Is there a new link for this. The current link is dead.

The link in DaveMcW's sig (in the post just above yours) does work for me.
