Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization algorithm"
"modified thermal regulation algorithm" » "modified thermal evolution algorithm", "modified thermal predation algorithm", "modified thermal estimation algorithm", "modified thermal degradation algorithm", "modified legal regulation algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified thermal regulation algorithm") OR ("modified notion optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified thermal regulation algorithm ) or ( modified notion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified thermal regulation algorithm") or ("modified notion optimisation algorithm"))*.
