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