Perhaps you should try some spelling variations:
"modified pulse optimization algorithms" » "modified pulse optimisation algorithm", "modified pulse estimation algorithms", "modified pulse estimation algorithm", "modified pulse optimisation algorithms", "modified pulse estimation algorithmss", "modified policy optimization algorithms", "modified game optimization algorithms", "modified qoe optimization algorithms", "modified male optimization algorithms", "modified passive optimization algorithms"
"modified multiobjective optimization algorithm" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"

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

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