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"
"parameters optimization algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameters optimization algorithms", "parameters optimisation algorithm", "parameters estimation algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("focusing optimization algorithmss") or ("parameters optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("focusing optimization algorithmss") OR ("parameters optimization algorithm")).
• Removing quotes may allow a broader search: (( focusing optimization algorithmss ) or ( parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("focusing optimization algorithmss") or ("parameters optimization algorithm"))*.
