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