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