Perhaps you should try some spelling variations:
"modified a estimation algorithmss" » "modified a estimation algorithms", "modified a estimation algorithm", "modified a optimization algorithms", "modified _ estimation algorithmss", "modified a destination algorithmss", "modified _ estimating algorithmss", "modified df estimation algorithmss", "modified adam estimation algorithmss"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

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