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