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