Perhaps you should try some spelling variations:
"allocation optimisation algorithmssss" » "allocation optimization algorithms", "allocation optimization algorithmssss", "allocation optimization algorithmsssss", "allocation estimation algorithmssss", "allocation estimation algorithmsssss"
"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 algorithmssss") OR ("parameters optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( allocation optimisation algorithmssss ) or ( parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("allocation optimisation algorithmssss") or ("parameters optimisation algorithm"))*.
