mxgmn / markovjunior Goto Github PK

Self explanatory, really. Downloaded the relase and it won't start.

images/CrossCountry.gif is reported missing when I forked the project.

I really love the work in MarkovJunior and I'd like to attempt rewriting it in Rust. My idea is to write fully unoptimized version without inference first and then learning from the process I'd attempt writing full library with optimizations and inference. I am having trouble understanding two concepts though.

Like in REFAL, Markov nodes can be nested: once we go into a child node, we ignore outer nodes until the child branch completes.

Why does nested MarkovNodes are prioritized when entered? I cannot see any advantage of this behaviour other than sometimes making the algorithm a bit more concise.

What exactly is union in terms of markov algorithms? I couldn't find any explaination online that would fit behaviour I see in some examples.

First off, very cool project @mxgmn!

I've been messing around with it today and had some questions and wanted to share some models I came up with. Issues aren't really the right format for that - would you be open to turning on the Discussions feature for this repo?

Hello. I can't understand ho to add some constraint for WFC. I want to generate river between two points, that points should be declared by me before start of programm.

While building on macos Catalina v 10.15.2
dotnet version : 6.0.300
build command : dotnet run --configuration Release MarkovJunior.csproj
getting the error:

Apartemazements > P = 16

I have tried to build with dotnet run --configuration Release MarkovJunior.csproj, but build failed with error message:

C:\Users\user\MarkovJunior\MarkovJunior.csproj : error NU1100: 'net6.0' に対する 'System.Drawing.Common (>= 4.5.1)' を解決できません。

It is Japanese, means "Could not resolve System,Drawing.Common for net 6.0".
Please correct if document is wrong.

How can i ran this programm on linux?
I tried wine, but its doesnt work(error on screenshot)

Hi, I appreciated your work very much. And I am interested in porting it to javascript and canvas which could run on a web browser.
Of course, I would also keep the original repo and license in the port version.

Take the simple Growth model for example, when you start the MJ it's all Bs on the grid so there's no "WB" to start with, so in what mechanism does MJ put a W in center (or via any other way) so that a "WB" can be matched therefore Growth can actually "grow"?

I guess the property "origin=True" might be the trick, but after a rough browsing I somehow can't find the right source (and it seems to me that it could be more "configurable" than just a boolean) to this design and I think this needs some serious explanation at the first section of the intro.

I'd love some documentation about the syntax of the model XML files. At the moment we can only deduce the nodes and parameters from the examples.

I can't help to suggest some small optimization suggestions I didn't dive deep into the code to see how these methods are used and maybe this is some unneeded optimization, but just in case :)

• For Power you can use Exponentiation by squaring.
• For weighted Random you can consider using ideas from this article.

Using map node with GUI seems to always crash, I'm running the MazeMap model.

When running this sequence with a size of say, 24x24x5:

<sequence values="WRBUPYA" origin="True">
            <one in="*****/*****/*****/*****/***** *****/*****/*****/*****/***** *****/*****/**R**/*****/*****"
                 out="*****/*****/**R**/*****/***** *****/*****/**R**/*****/***** *****/*****/**R**/*****/*****" symetry="()"/>
</sequence>

I get the "origin" voxel replaced by a 3 voxel bar in any of all the possible directions.
Shouldn't empty symmetry mean a literal match for the rule template?
I only what a vertical 3 voxel pillar.

Hey guys,

Amazing tool. I generated several CarmaTowers and I was greatly impressed with the results.

That said, I've read most of the documentation, and yet I'm still not able to wrap my head around the process of creating a custom model with its own rules/constraints/MagicaVoxel pieces. In other words, I'm looking to generate my own CarmaTower-type buildings, but the XML of CarmaTower.xml is a tad cryptic at the moment, especially without any documentation.

I know this was just released, so please tell me if it's too early to attempt such a thing.

Thanks a ton!

I want to visualize it as it runs and be able to choose which model to run. Is there an option for that?

The file name was SeaVilla_1058505240.vox, if that tells you anything useful. Idk if this is a bug or not, but I figured you might be interested either way.

Hello,

I can't seem to figure out how to run the GUI. The code seems to be included in the source, but I haven't a clue on how to get it to start.

Hi,

Thanks for your recent effort in documenting this project. I have an intern tinkering with this (@GraceMagnyFokam) and we're getting some unexpected behavior. For instance

<one p="0.1"> 

does not seem to work. In addition <prl p="0.1" steps="1"> seems to fill the whole screen? I'm sorry I am passing on this information secondhand, but hoping you had some insight.

Thanks!
Dylan

I run dotnet run --configuration Release MarkovJunior.csproj but nothing happens, what do display the GUI?

When trying to run Program.Main on Linux with net6.0 I get an exception.

Unfortunately Microsoft has decided to remove System.Drawing on all operating systems except Windows.

Seems all rules in one node have the same possibility to be executed, so does the all node.
How can I define a node like 10% probability to do B=R and 90% to do B=G?

I just built the repo (mac ventura) but not sure what the next steps are. Sorry if this is a silly question. Is there an application?

Hello, after read the introduction, I think this is a great project for unity games, will you make an example for unity in the future?

Thanks.

Cloned the repo to do some playing around on my own and got an exception when I ran the project for the first time with dotnet run --configuration Release MarkovJunior.csproj.

Seems like this is some sort of issue with the GUI not initializing correctly. Not too knowlegable in .NET, C#, or this project so if there's something simple I'm missing I apologize.
