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

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

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