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