Description

Version 4.7.4 provides differential equation completeness improvements

  • [Tactics] Improved equality rewriting: support for rewriting in bound occurrences of the form y=x ==> \\forall x x<y and y=x ==> [a(x)]x<y
  • [Tactics] Improved Barrier and ODE invariant completeness: automated constification of unchanged (non-primed) variables x to nullary function symbols x() now proves more ODEs automatically
  • [Tactics] Differential weakening: fast dW preserves only constants, complete dWplus preserves all initial state
  • [Tactics] Differential ghost: extended unification for division with variations of the shape y' = y/a + b
  • [Backend] (Fix) Initialize a single Mathematica/Wolfram Engine instance to avoid startup hickups with restricted licenses
  • [Backend] (Fix) Wait for backend to stay alive
  • [Printer] (Fix) Archive printer: export hybrid program definition names without ()
  • [Server] (Fix) Avoid infinite startup when running command line tools (parse, prove etc.)
