Perhaps you should try some spelling variations:
"modified made optimization algorithms" » "modified made optimisation algorithm", "modified made estimation algorithms", "modified made estimation algorithm", "modified made optimisation algorithms", "modified made estimation algorithmss", "modified game optimization algorithms", "modified market optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms", "modified adam optimization algorithms", "modified df optimization algorithms"
"modified parameter optimization algorithm" » "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameter estimation algorithms", "modified parameters optimization 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 made optimization algorithms") OR ("modified parameter optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified made optimization algorithms ) or ( modified parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made optimization algorithms") or ("modified parameter optimization algorithm"))*.
