Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified adaptive evolutionary algorithm" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified objective evolutionary algorithm", "modified passive evolutionary algorithm"

Try widening your search to All Fields.

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

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