Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified changing optimized algorithms" » "modified changing optimized algorithm", "modified changing optimizer algorithms", "modified choosing optimizer algorithms", "modified caging optimized algorithms"

Try widening your search to All Fields.

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

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