Perhaps you should try some spelling variations:
"modified parameter optimizer algorithmss" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimized algorithmss", "modified parameter optimization algorithmss"
"modified allocation optimizer algorithms" » "modified allocation optimization algorithms", "modified allocation optimized algorithms", "modified allocation optimized 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 parameter optimizer algorithmss") or ("modified allocation optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimizer algorithmss") OR ("modified allocation optimizer algorithms")).
• Removing quotes may allow a broader search: (( modified parameter optimizer algorithmss ) or ( modified allocation optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimizer algorithmss") or ("modified allocation optimizer algorithms"))*.
