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 algorithmssssssssss" » "same optimization algorithmsssssssssss", "same estimation algorithmssssssssss", "same estimation algorithmsssssssssss", "game optimization algorithmssssssssss", "stage optimization algorithmssssssssss", "_ optimisation algorithmssssssssss"

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