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