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

You may be able to get more results by adjusting your search query.

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