Abstract From the Canadian patent

A method of combinatorial multimodal optimisation uses a genetic algorithm to find simultaneous global optimal solutions to combinatorial problems. Each individual within the population is associated not only with a fitness value but with a fitness vector, using which the persistence of all of the best individuals into the next generation can be guaranteed. Phenotype as well as genotype analysis is an integral part of the method.

Why it's free to use

  • Filed March 12, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 12, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 12, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
