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