Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified total variation algorithms" » "modified total estimation algorithms", "modified total vision algorithms", "modified total approximation algorithms", "modified global variation algorithms", "modified thermal variation algorithms", "modified ti6al4v variation 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 multiobjective optimized algorithm") OR ("modified total variation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithm\") OR (\"modified total variation algorithms\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) OR ( modified total variation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") OR ("modified total variation algorithms"))*.
