Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithm"
"modified caging evolutionary algorithm" » "modified caging evolution algorithm", "modified caging solution algorithm", "modified aging evolutionary algorithm", "modified changing evolutionary algorithm", "modified charging evolutionary algorithm"

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 evolutionary algorithm") or ("modified parameters optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging evolutionary algorithm") OR ("modified parameters optimization algorithm")).
• Removing quotes may allow a broader search: (( modified caging evolutionary algorithm ) or ( modified parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging evolutionary algorithm") or ("modified parameters optimization algorithm"))*.
