Perhaps you should try some spelling variations:
"notion optimization algorithmssssssssssssssss" » "notion optimization algorithmsssssssssssssssss", "notion optimisation algorithmssssssssssssssss", "notion estimation algorithmssssssssssssssss", "network optimization algorithmssssssssssssssss", "policy optimization algorithmssssssssssssssss"
"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.

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