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 optimisation algorithmsssssssssssss" » "notion optimization algorithmssssssssssssss", "notion estimation algorithmsssssssssssss", "notion estimation algorithmssssssssssssss", "network optimization algorithmsssssssssssss"

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