Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"code using mental algorithm" » "code using genetic algorithm", "code using control algorithm", "code using mppt algorithm", "code using metal algorithm", "code nursing mental algorithm", "code using medical algorithm", "core using mental algorithm"

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

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