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

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