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