Perhaps you should try some spelling variations:
"modified changing optimization algorithmss" » "modified changing optimisation algorithm", "modified changing estimation algorithms", "modified changing estimation algorithm", "modified changing optimisation algorithms", "modified changing estimation algorithmss", "modified staffing optimization algorithmss", "modified caging optimization algorithmss"
"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"

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