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

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