Perhaps you should try some spelling variations:
"notion optimization algorithmssssssssssssss" » "notion optimisation algorithmsssssssssssss", "notion estimation algorithmssssssssssssss", "notion estimation algorithmsssssssssssss", "network optimization algorithmssssssssssssss", "policy optimization algorithmssssssssssssss"
"allocation optimization algorithms" » "allocation optimisation algorithm", "allocation estimation algorithms", "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 algorithmssssssssssssss\") OR (\"allocation optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( notion optimization algorithmssssssssssssss ) OR ( allocation optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("notion optimization algorithmssssssssssssss") OR ("allocation optimization algorithms"))*.
