This release introduces "MaxDestroyerEvents" stopping condition to WolframModel. It allows one to generate partial multihistories (local multiway systems), which are intermediate between "GlobalMultiway" and "MultiwaySpacelike" event selection functions:

In[] := WolframModel[
    {{1, 2}, {2, 3}} -> {{1, 3}},
    Partition[Range[10], 2, 1],
    <|"MaxDestroyerEvents" -> 2|>,
    "EventSelectionFunction" -> "MultiwaySpacelike"][
  "ExpressionsEventsGraph", VertexLabels -> Automatic]

Kudos to @daneelsan for implementing this feature!

This release introduces CausalDensityDimension which allows one to estimate Myrheim-Meyer dimension of causal graphs:

Needs["GeneralUtilities`"];
dimensionsPlot[rule_, init_, generationCount_, eventOrderingFunction_, sampleSize_] := ModuleScope[
  history = WolframModel[rule, init, generationCount, "EventOrderingFunction" -> eventOrderingFunction];
  eventRangesForGenerations = # + {1, 0} & /@ Partition[Accumulate @ history["GenerationEventsCountList"], 2, 1];
  causalGraph = history["CausalGraph"];
  dimensionsForGenerations = Join[
    {Missing[]},
    MeanAround /@
      ParallelMap[CausalDensityDimension[causalGraph, {1, #}] &,
          RandomSample[#, UpTo[sampleSize]] & /@ Range @@@ eventRangesForGenerations,
          {2}]];
  ListPlot[dimensionsForGenerations, PlotRange -> All, Frame -> True, FrameLabel -> {"Generations", "Dimension"}]
];
In[] := dimensionsPlot[
  {{1, 2, 3}, {4, 3, 5}} -> {{6, 3, 7}, {6, 1, 2}, {3, 4, 1}}, {{1, 1, 1}, {1, 1, 1}}, 60, Automatic, 30]

In other news:

  • "FeatureAssociation" property allows one to extract an association with named features (more work still needs to be done on the features themselves).
  • More functions now support syntax autocompletion.
  • We improved the usage messages and function templates to use more descriptive argument names.
  • WolframPhysicsProjectStyleData is now renamed to SetReplaceStyleData. The old name still works for backwards compatibility.

Thanks to @SantiagoGiner, @mrektor, and @daneelsan for contributing to this release!

AcyclicGraphTake and Consistency Improvements

This release introduces:

  • AcyclicGraphTake function that allows one to easily take "causal diamonds" between two vertices of a DAG:
In[] := With[{
    graph = WolframModel[
        {{{1, 2}, {1, 3}, {1, 4}} -> {{2, 2}, {2, 5}, {3, 2}, {3, 4}, {4, 5}}}, {{1, 1}, {1, 1}, {1, 1}}, 15][
      "CausalGraph", VertexStyle -> LightGray, EdgeStyle -> Gray]},
  HighlightGraph[graph, AcyclicGraphTake[graph, {4, 268}]]
]

Thanks to @SantiagoGiner, @daneelsan and @aokellermann for contributing to this release!

Internal Improvements

In this release, we focused on the improvements to the development process, testing, and refactoring.

Some notable changes are:

  • WolframModelPlot is now renamed back to HypergraphPlot. The old name still works for backward compatibility.
  • Stability improvements for the case where multiple versions of the paclet are installed simultaneously.
  • More consistent style in the usage messages.

If you are a developer, here are some of the improvements to the workflow:

  • A new build system that, among other things, allows you to rebuild libSetReplace automatically by simply running
Get[FileNameJoin[{$SetReplaceRoot, "Kernel", "init.m"}]]
  • Multi-platform paclets for all builds (that is, all commits on all branches) are now automatically created by Circle CI.
  • We extended the linter to format bash and Markdown code and check the line width. There are also now git hooks for automatically checking for linting issues before a push and automatically formatting before a commit.

We also started working on a feature extractor that would allow one to use machine learning functions with Wolfram models. The work on that is in the early stage of development.

Kudos to @mrektor, @taliesinb, @daneelsan, and @aokellermann for contributing to this release!

We now have RandomHypergraph! You can either specify a signature or a single number to vary the arities randomly:

In[] := WolframModelPlot @ RandomHypergraph[1000]

HypergraphToGraph & IsomorphicHypergraphQ

This release introduces HypergraphToGraph. It can convert ordered hypergraphs to graphs in multiple ways, either preserving distances or in a lossless way:

In[] := Graph3D @ HypergraphToGraph[
  WolframModel[
    {{1, 2, 2}, {3, 4, 5}} -> {{5, 6, 6}, {7, 2, 5}, {8, 2, 6}, {2, 1, 3}}, Automatic, 50, "FinalState"],
  "StructurePreserving"]

image

Thanks to that lossless conversion, we now also have IsomorphicHypergraphQ.

Also, we added "MultiwayQ" property, which can tell you if a given evolution contains any multiway branching.

Kudos to @wawo9193, @daneelsan, and @taliesinb for contributing to this release!

In addition to improvements to stability and performance, we have introduced the IndexHypergraph function:

In[] := IndexHypergraph[{{a, b, c}, {b, d, e}, {c, f, g}}]
Out[] = {{1, 2, 3}, {2, 4, 5}, {3, 6, 7}}

Also, you can now pass evolution objects directly to RulePlot:

Subhypergraph & Performance Improvements

In this release, we focused on stability, performance, and streamlining SetReplace for our users and developers:

  • We introduced Subhypergraph and WeakSubhypergraph functions.

    In[] := With[{
        evolution = WolframModel[{{1, 2}, {2, 3}} -> {{4, 2}, {4, 1}, {2, 1}, {3, 4}}, Automatic, Automatic]},
      evolution["FinalStatePlot",
                EdgeStyle -> LightGray,
                GraphHighlight -> WeakSubhypergraph[evolution["FinalState"], Range[9, 16]]]]
    image
  • We have a new event ordering function called "Any", which generates an undefined evolution order. There is not much use for it yet, but it paves the road for some powerful optimizations in the future.

  • You can now use VertexLabels -> "Index" in "ExpressionsEventsGraph" that displays the indices of events and expressions in a much more compact way than VertexLabels -> "Name".

We also did some weed whacking:

  • ./build.wls script should no longer fail if the repository is located under a symbolic link.

  • Vertex names which are themselves lists now work correctly in WolframModel.

Huge thanks to @aokellermann and @daneelsan for contributing to this release!

SetReplace is now fully compatible with Wolfram Language version 12.2.

If you were running 12.2 and were having issues with WolframModelPlot, these are now resolved.

Event Deduplication

This release introduces event deduplication. If two events have the same set of inputs and the outputs identical up to the renaming of new atoms, they can now be deduplicated using "EventDeduplication" -> "SameInputSetIsomorphicOutputs".

In[] := WolframModel[{{1, 2}, {1, 3}} -> {{1, 2}, {1, 4}, {2, 4}, {3, 
     4}}, {{1, 1}, {1, 1}}, 3, 
  "EventSelectionFunction" -> "MultiwaySpacelike", 
  "EventDeduplication" -> 
   "SameInputSetIsomorphicOutputs"]["ExpressionsEventsGraph", 
 GraphLayout -> "SpringElectricalEmbedding"]

image

Also, the weed where the output graph's size would reset after each re-evaluation is now fixed.
