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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"notion optimization algorithmsssssssssss\") OR (\"allocation optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( notion optimization algorithmsssssssssss ) OR ( allocation optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("notion optimization algorithmsssssssssss") OR ("allocation optimization algorithm"))*.
