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

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