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"
"same optimisation algorithmssssssssssss" » "same optimization algorithmsssssssssssss", "same estimation algorithmssssssssssss", "same estimation algorithmsssssssssssss", "game optimization algorithmssssssssssss", "stage optimization algorithmssssssssssss", "_ optimisation algorithmssssssssssss"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("same optimisation algorithmssssssssssss") or ("parameters optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("same optimisation algorithmssssssssssss") OR ("parameters optimisation algorithm")).
• Removing quotes may allow a broader search: (( same optimisation algorithmssssssssssss ) or ( parameters optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("same optimisation algorithmssssssssssss") or ("parameters optimisation algorithm"))*.
