Perhaps you should try some spelling variations:
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"
"modified global variation algorithm" » "modified global estimation algorithm", "modified global predation algorithm", "modified total variation algorithm", "modified global edition 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 objective estimation algorithms") OR ("modified global variation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified global variation algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified global variation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified global variation algorithm"))*.
