Perhaps you should try some spelling variations:
"notion optimisation algorithmssssssssssss" » "notion optimization algorithmsssssssssssss", "notion estimation algorithmssssssssssss", "notion estimation algorithmsssssssssssss", "network optimization algorithmssssssssssss"
"parameter optimisation algorithm" » "parameter optimization algorithms", "parameter estimation algorithm", "parameter estimation algorithms", "parameter optimization 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 optimisation algorithmssssssssssss") or ("parameter optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("notion optimisation algorithmssssssssssss") OR ("parameter optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( notion optimisation algorithmssssssssssss ) or ( parameter optimisation algorithm ))*.
