Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"
"modified staffing optimized algorithms" » "modified staffing optimized algorithm", "modified staffing optimizer algorithms", "modified staffing optimization algorithms", "modified caging optimized algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified staffing optimized algorithms") OR ("modified parameters optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified staffing optimized algorithms\") OR (\"modified parameters optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified staffing optimized algorithms ) OR ( modified parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified staffing optimized algorithms") OR ("modified parameters optimization algorithms"))*.
