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 nodal optimisation algorithms" » "modified nodal optimization algorithms", "modified nodal estimation algorithms", "modified nodal estimation algorithm", "modified nodal optimization algorithmss", "modified nodal estimation algorithmss", "modified global optimization algorithms", "modified adam optimisation algorithms", "modified near optimisation algorithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified nodal optimisation algorithms") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified nodal optimisation algorithms") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified nodal optimisation algorithms ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified nodal optimisation algorithms") or ("modified multiobjective optimisation algorithm"))*.
