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 algorithmsssssssssssssss" » "notion optimization algorithmssssssssssssssss", "notion estimation algorithmsssssssssssssss", "notion estimation algorithmssssssssssssssss", "network optimization algorithmsssssssssssssss"

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