Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified changing optimized algorithms" » "modified changing optimized algorithm", "modified changing optimizer algorithms", "modified changing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimized algorithms"

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 parameters optimisation algorithm") OR ("modified changing optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameters optimisation algorithm ) or ( modified changing optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimisation algorithm") or ("modified changing optimized algorithms"))*.
