Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"modified topology optimisation algorithm" » "modified topology optimization algorithms", "modified topology estimation algorithm", "modified topology estimation algorithms", "modified topology optimization algorithm", "modified policy optimization algorithm"

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

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