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

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 optimization algorithmssssssssss") OR ("parameter optimization algorithm"))~.
• Removing quotes may allow a broader search: (( allocation optimization algorithmssssssssss ) or ( parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("allocation optimization algorithmssssssssss") or ("parameter optimization algorithm"))*.
