Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"modified up solution algorithm" » "modified up evolution algorithm", "modified up convolution algorithms", "modified up evolutionary algorithm", "modified _ solution algorithm", "modified df solution algorithm", "modified bi1 solution algorithm", "modified up solutions algorithm", "modified drug solution 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 up solution algorithm") OR ("modified objective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified up solution algorithm\") OR (\"modified objective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified up solution algorithm ) OR ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified up solution algorithm") OR ("modified objective optimization algorithms"))*.
