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

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("notion optimisation algorithmssssssssssssssssss") OR ("parameters optimization algorithms"))~.
• Removing quotes may allow a broader search: (( notion optimisation algorithmssssssssssssssssss ) or ( parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("notion optimisation algorithmssssssssssssssssss") or ("parameters optimization algorithms"))*.
