Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"error control method algorithm" » "error control mom algorithm", "error control methods algorithm", "export control method algorithm", "order control method 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: "((\"error control method algorithm\") OR (\"modified multiobjective optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( error control method algorithm ) OR ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("error control method algorithm") OR ("modified multiobjective optimization algorithms"))*.
