Ah! Thanks! I'll fix that.

Oh! I had them swapped. That makes more sense now. Are you sure? The part.cfg file says "mass = 0.05". Yea, something I had disabled at one point for testing. Fixed. I'll add it to the list. But I am hesitant on adding stage specific configurations for fear of making the tool too complex. Perhaps I need an advanced mode. Thank you! And thanks for your help on this! Your original graphs are what inspired me to write this tool.

Yes, that's correct. Yea, I meant that to add that. Fixed.

Yes, it would be a single stack. This attempt has no asparagus because the design chose a solid rocket booster which can't be asparagused to. However, more importantly, you entered the weight as tons when (at the time) the tool expected kilograms. I realize people are likely to make this mistake frequently, so I change the tool to accepts tons now. Try it again. Thanks so much!

The list is already sorted, and you can choose the order by changing the "Optimize for" setting at the top. It wouldn't make sense to sort by dV as you would end up getting infinitely larger rockets.

And drain your battery no doubt. $#|%! My bad. I can't believe I never noticed that. Now fixed. Yea, I didn't think of that. I switched everything over to use tons now. Thank you for noticing this! It turns out there was a bug that would occur for tiny payloads. It's now been fixed. That's a good idea actually. Done! That sounds like a challenge Thanks again!

KSP Optimal Rocket Calculator v1.20 for Kerbal Space Program 1.0.5 http://garycourt.github.io/korc/ The KSP Optimal Rocket Calculator (KORC) is a web app that allows you to quickly find the most mass or cost efficient rocket, for a given payload, with the parts you have unlocked or installed. Here's how to use it: Open http://garycourt.github.io/korc/ in a modern web browser. Enter the mass (in metric tons) of the payload you are trying to move. Enter the minimum amount of Delta-V you need to accelerate it. If you are launching your payload from a planet, select the planet, or enter the force of gravity at your launch point. Select which parts you have unlocked, or mods you have installed. Hit search and watch the result come in! If your rocket has more then one stage, you will see a list of possible designs at the bottom of the page, ordered by most to least efficient. The program will constantly keep generating new designs, and displays only the top 20 most efficient ones. You can hit stop at any time if you see one you like. Now that you've figured it out, there are many more other constraints you can configure: What metric you would like to optimize your rocket for. The minimum (and optionally, maximum) thrust-to-weight ratio you need all stages of the rocket to produce. Remember that this must be greater then 1 to leave the surface of your selected planet. This field has no affect if there is no gravity. The maximum number of stages you want your rocket to have. Keep this number low as it increases the calculation times exponentially. If you would like your rocket to use asparagus staging (all engines fire at once, fuel is taken from outer stages first). This always produces lighter rockets and the cost of greater complexity. Have all calculations use the engine's atmospheric stats. This is not normally needed as most delta-V cheat sheets use vacuum stats. And many more! Be aware that this program runs locally in your web browser, and will max out your CPU while running. Don't forget to click "Stop" before switching back to Kerbal Space Program! If you are getting wildly different numbers in Kerbal Engineer, it's likely that you've enabled Atmospheric Stats in one tool and not the other. Or else you've messed up your staging.

Roadmap There's still a few things I'd like to add to this tool before I'm done: Support parallel staging (all stages fire at same time) Add option for adding size adapters Serialize and output arguments used (for debugging) Output stats of parts in the parts list (for debugging) Add parts from other mods Support per stage settings Quickly toggle parts by size or science node Support This Project Find this tool useful? Like to see it continually supported? I am a self-employed software developer who built this in my free time. Unfortunately, I can't work on stuff like this all the time as I have to make money to eat and live. With your support, I can continue working on this and other great tools for Kerbal Space Program that everyone can benefit from! Please click the "Donate" link on the web app to support this project!
