Perhaps you should try some spelling variations:
"notion optimization algorithmssssss" » "notion optimization algorithms", "notion optimisation algorithm", "network optimization algorithmssssss", "policy optimization algorithmssssss", "allocation optimization algorithmssssss"
"parameters estimation algorithms" » "parameter estimation algorithms", "parameter estimates algorithms", "parameter optimization algorithms", "parameters estimation algorithm", "parameters optimization algorithms", "parameters optimisation 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 algorithmssssss") OR ("parameters estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"notion optimization algorithmssssss\") OR (\"parameters estimation algorithms\"))".
• Removing quotes may allow a broader search: (( notion optimization algorithmssssss ) OR ( parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("notion optimization algorithmssssss") OR ("parameters estimation algorithms"))*.
