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

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 (\"parameters optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( notion optimization algorithmssssssssssssss ) OR ( parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("notion optimization algorithmssssssssssssss") OR ("parameters optimisation algorithm"))*.
