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"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified male optimization algorithm") or ("modified notion estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified male optimization algorithm") OR ("modified notion estimation algorithms")).
• Removing quotes may allow a broader search: (( modified male optimization algorithm ) or ( modified notion estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified male optimization algorithm") or ("modified notion estimation algorithms"))*.
