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

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