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