Perhaps you should try some spelling variations:
"modified make optimization algorithms" » "modified make estimation algorithms", "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 network optimisation algorithm" » "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation 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 make optimization algorithms") OR ("modified network optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified make optimization algorithms\") OR (\"modified network optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified make optimization algorithms ) OR ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified make optimization algorithms") OR ("modified network optimisation algorithm"))*.
