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