Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified changing optimizer algorithms" » "modified changing optimized algorithms", "modified changing optimized algorithm", "modified changing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimizer 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 changing optimizer algorithms") OR ("modified parameter optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified changing optimizer algorithms\") OR (\"modified parameter optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified changing optimizer algorithms ) OR ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified changing optimizer algorithms") OR ("modified parameter optimization algorithm"))*.
