Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified market optimization algorithm" » "modified market optimization algorithms", "modified market optimisation algorithm", "modified market estimation algorithm", "modified game optimization algorithm", "modified parameter optimization algorithm", "modified market capitalization algorithm", "modified male optimization 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 algorithm\") OR (\"modified market optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( modified market optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("modified market optimization algorithm"))*.
