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 algorithm", "modified multiobjective estimation algorithms"
"modified bi1 optimisation algorithms" » "modified bi1 optimization algorithms", "modified bi1 estimation algorithms", "modified bi1 estimation algorithm", "modified bi1 optimization algorithmss", "modified bi1 estimation algorithmss", "modified _ optimisation algorithms", "modified _ optimization algorithms", "modified qoe optimization algorithms"

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 bi1 optimisation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) OR ( modified bi1 optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") OR ("modified bi1 optimisation algorithms"))*.
