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