    Optimal MGA and MGA-1DSM trajectories - PyKEP/PyGMO

    This made me thinking about if the accuracy can be improved. I don't think that moving the optimization towards n-body would be feasible, but improvements in the approximation model might be possible. Keithth G., can you elaborate on 'patched conics' vs. 'linked conics' model? First of all, I...

    GravityAssistMFD-0.2 Hello everyone, disappeared a bit, had to earn money and things :) Thanks to Boogabooga's advices regarding UI, and DSMs, here is version 0.2 of GravityAsistMFD, which makes optimization a bit friendlier for people with weaker machine. Changes 1. The Departure and Arrival...

    Ok, then I get what you mean, and I see no problem with making it possible, I'll need to touch the PaGMO code as well for this, as this affects the decision vector, and the dimension of the problem as well. But it makes sense perfectly. I think the approach will be to merge the MGA and MGA-1DSM...

    Optimal MGA and MGA-1DSM trajectories - PyKEP/PyGMO

    Hmm, I'm not sure I understand. The time of DSMs is part of the decision vector, and subject to optimisation as well. I also noticed, that very often, practically 0 deltaV DSMs are added, which are considered to be noise. But if you do MGA-1DSM optimisation, theoretically there is a DSM during...

    Thanks for the feedback, it makes perfect sense, any comment of this kind is greatly appreciated.

    Ok, you should be fine with 1 islands in that case, but definitely decrease it to 1. The number of islands is just to allow utilising your full computing power, it's for parallelism. There will be a proper standalone tool as well which you can run outside of orbiter, but it's right now only...

    Interesting, did you get notified that VC Redist is needed, or just figured it out? Well yes, it'll use your iron a lot when you are running optimisation, GlobOpt is resource intensive thing. You shouldn't feel it though when you are just using existing solution. It's mainly the resource...

    Well, I'm in a bit of a trouble then now, since it shows up for me. Something crashes into itself during InitModule call. crap... Not sure what to do at this point, so I suppose that's it for now :(. At least the packager now packages all necessary dlls.

    Ok, this was the final. I took some extra precautions now, renaming folders where the DLLs are, and trying to run that way. https://github.com/tuzcsaba/orbiter-kep/blob/master/Install-Package/GravityAssistMFD-0.13.zip Upcoming rounds will be quicker. [EDIT] Probably leftover from previous...

    GravityAssistMFD-0.11 So, as I promised, I fixed the few hiccups you came back with (Thank you for those). GravityAssistMFD-0.11 https://github.com/tuzcsaba/orbiter-kep/blob/master/Install-Package/GravityAssistMFD-0.11.zip Changelog: - Added the missing MinGW dlls - Removed unnecessary...

    I only tested this with D3D9Client, without Graphic client, Modules/Server is probably not on the library path. I have the issue too if I start orbiter.exe. I probably have to check on the linkage for Modules which should run under both stock rendering and Graphic engines. Also, please note...

    Oh damn dynamic libraries. Of course MinGW had a lurking DLL in it's lib folder which was on my library path. Sure thing. Right, GPL. I think I can pack it up with the depdendencies bundled, so that it's possible to work with it without MinGW. I'll see to it, it violates license like this...

    GravityAssistMFD-0.1 So, here's the basic idea, but it's a nothing yet, a simple prototype. I did went to Jupiter on the Galileo track with it though, so it's definitely usable already to some degree. Usage in a nutshell So you copy the things in the ZIP in your Orbiter root folder as usual...

    Enjo, ADSWNJ, Keithth G, thanks for all so far. I expect that I'll disappear with this thing for a while, and report back once I have something worthy of showing. We can get back to the interfacing matters at that point. I will expose data from my DLL, but I don't want to get into possible...

    Hard part over, now the tedious part comes. Ideas appreciated Hi. This is my last post on this thread, last piece of news. Further posting will be related to the so called GravityAssistModule, which provides: - A DLL and headers, to integrate in any Orbiter Module, which solve the MGA and...
