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