Perhaps you should try some spelling variations:
"modified make optimization algorithms" » "modified make optimisation algorithm", "modified make estimation algorithms", "modified make estimation algorithm", "modified make optimisation algorithms", "modified make estimation algorithmss", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms"
"defined network optimization algorithm" » "defined network optimisation algorithm", "defined network estimation algorithm", "defined network estimation 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 make optimization algorithms") or ("defined network optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified make optimization algorithms") OR ("defined network optimization algorithm")).
• Removing quotes may allow a broader search: (( modified make optimization algorithms ) or ( defined network optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified make optimization algorithms") or ("defined network optimization algorithm"))*.
