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