Constructors

KamadaKawai

Fields

• kk_seed :: !(Maybe [(Double, Double)])
• kk_nIter :: !Int
• kk_sigma :: Int -> Double

  The base standard deviation of position change proposals

• kk_startTemp :: !Double

  The initial temperature for the annealing

• kk_coolFact :: !Double

  The cooling factor for the simulated annealing

• kk_const :: Int -> Double

  The Kamada-Kawai vertex attraction constant

LGL

Fields

• lgl_nIter :: !Int
• lgl_maxdelta :: Int -> Double

  The maximum length of the move allowed for a vertex in a single iteration. A reasonable default is the number of vertices.

• lgl_area :: Int -> Double

  This parameter gives the area of the square on which the vertices will be placed. A reasonable default value is the number of vertices squared.

• lgl_coolexp :: !Double

  The cooling exponent. A reasonable default value is 1.5.

• lgl_repulserad :: Int -> Double

  Determines the radius at which vertex-vertex repulsion cancels out attraction of adjacent vertices. A reasonable default value is area times the number of vertices.

• lgl_cellsize :: Int -> Double
