RulePlot

RulePlot[sys]

generates a plot representing the rule for the computational system sys.

RulePlot[sys,init,t]

generates a plot of the evolution of the system sys from initial condition init for t steps.

RulePlot[sys,evol]

generates a plot of the evolution evol assuming it is derived from a system of the form sys.

Details and Options

  • Possible computational systems sys include:
  • CellularAutomaton[spec]cellular automaton
    TuringMachine[spec]Turing machine
    SubstitutionSystem[spec]substitution system
    BooleanFunction[spec]Boolean function
  • TuringMachine[{rule,s,k}] can be used to specify a Turing machine in which rule does not uniquely specify a transformation for each of the s k possible configurations, but that nevertheless will be rendered assuming s head states and k tape colors.
  • RulePlot works with 1D and 2D systems.
  • Options include:
  • Appearance Automaticoverall appearance
    ColorRules Automaticrules for determining colors from values
    Frame Automaticwhether to draw a frame around rule cases
    FrameStyle Automaticthe style to use for a frame
    Mesh Automaticwhether to draw a mesh
    MeshStyle Automaticthe style to use for a mesh
    PlotLegends Nonelegends to include
    PlotMarkers Automaticmarkers for Turing machines, etc.
    PlotTheme $PlotThemeoverall theme for the rule plot
    Spacings Automatichorizontal and vertical spacings
  • Possible appearance elements include:
  • "Contiguous"no space between states
    "Stacked"small space between states
    "Arrow"draw an arrow between states
    "Squares"squares for cells
    "Bricks"bricks for cells
    "Hexagons"hexagons for cells
    "Simplified"simplified rule cases
    "Short"show shortened list of rules
  • Possible plot legend forms include:
  • "Icon"use an icon as the legend
    "Text"use text as the legend
    exprarbitrary plot legend
  • In the form RulePlot[sys,evol], specific rules are typically ignored; only the implicit or explicit specification of number of colors, states, etc. is used.
