Perhaps you should try some spelling variations:
"allocation optimisation algorithm" » "allocation optimization algorithm", "allocation optimization algorithms", "allocation estimation algorithm", "allocation estimation algorithms"
"parameter optimisation algorithmssssssssssss" » "parameter optimization algorithmsssssssssssss", "parameter estimation algorithmssssssssssss", "parameter estimation algorithmsssssssssssss", "parameter optimization 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: (("allocation optimisation algorithm") or ("parameter optimisation algorithmssssssssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("allocation optimisation algorithm") OR ("parameter optimisation algorithmssssssssssss")).
• Removing quotes may allow a broader search: (( allocation optimisation algorithm ) or ( parameter optimisation algorithmssssssssssss )).
• Adding a wildcard symbol may retrieve word variants: (("allocation optimisation algorithm") or ("parameter optimisation algorithmssssssssssss"))*.
