Perhaps you should try some spelling variations:
"modified nodal optimisation algorithm" » "modified nodal optimization algorithms", "modified nodal estimation algorithm", "modified nodal estimation algorithms", "modified global optimization algorithm", "modified adam optimisation algorithm", "modified near optimisation algorithm"
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation 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 algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified nodal optimisation algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified nodal optimisation algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified nodal optimisation algorithm") or ("modified multiobjective optimization algorithm"))*.
