Perhaps you should try some spelling variations:
"modified large optimization algorithms" » "modified large optimisation algorithm", "modified large estimation algorithms", "modified large estimation algorithm", "modified large optimisation algorithms", "modified large estimation algorithmss", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified large optimization algorithms") or ("modified objective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified large optimization algorithms") OR ("modified objective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified large optimization algorithms ) or ( modified objective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified large optimization algorithms") or ("modified objective optimization algorithm"))*.
