Perhaps you should try some spelling variations:
"modified male optimization algorithm" » "modified male optimization algorithms", "modified male optimisation algorithm", "modified male estimation algorithm", "modified game optimization algorithm", "modified market optimization algorithm", "modified stage optimization algorithm"
"model using methods algorithm" » "model nursing methods algorithm", "model making methods algorithm", "model counting methods algorithm", "code using methods algorithm", "models nursing methods algorithm", "powder using methods algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("model using methods algorithm") OR ("modified male optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using methods algorithm\") OR (\"modified male optimization algorithm\"))".
• Removing quotes may allow a broader search: (( model using methods algorithm ) OR ( modified male optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("model using methods algorithm") OR ("modified male optimization algorithm"))*.
