Perhaps you should try some spelling variations:
"notion optimization algorithmssssssssssssss" » "notion optimization algorithmsssssssssssssss", "notion optimisation algorithmssssssssssssss", "notion estimation algorithmssssssssssssss", "network optimization algorithmssssssssssssss", "policy optimization algorithmssssssssssssss"
"allocation optimization algorithm" » "allocation optimization algorithms", "allocation optimisation algorithm", "allocation estimation algorithm"

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

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