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