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