Perhaps you should try some spelling variations:
"parameters optimisation algorithmssssssss" » "parameter optimization algorithmssssssss", "parameter estimation algorithmssssssss", "parameters optimization algorithmsssssssss", "parameters estimation algorithmssssssss", "parameters estimation algorithmsssssssss"
"allocation optimisation algorithm" » "allocation optimization algorithm", "allocation optimization algorithms", "allocation estimation algorithm", "allocation estimation algorithms"

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