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