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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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"))*.
