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