Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified thermal solution algorithm" » "modified thermal evolution algorithm", "modified thermal convolution algorithms", "modified thermal evolutionary algorithm", "modified chemical solution algorithm", "modified optimal solution algorithm", "modified minimal solution algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithms\") OR (\"modified thermal solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( modified thermal solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("modified thermal solution algorithm"))*.
