Abstract From the Canadian patent

A cellular automaton part is provided with cellular automata each including a plurality of cells. Each cell is provided with a growth period state deriving circuit for growing a cell column and a stable period state deriving circuit for stabilizing the cell column. An input/output part carries out input/output in/from the cellular automata in relation to a target problem and, outputs the same also to an evaluation part. The evaluation part operates the degrees of application of the cellular automata with respect to the target problem so, that an evaluation reflecting part decides next initial states of the cellular automata and operations of the growth period and stable period state …

Why it's free to use

  • Filed October 3, 1994 and granted July 27, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 3, 2014.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 3, 2016.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
