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