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"
"coarse grain method algorithm" » "coarse grain mom algorithm", "coarse grain motion algorithm", "coarse graining methods algorithm", "coarse group method algorithm", "course grain method algorithm"

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: (("coarse grain method algorithm") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("coarse grain method algorithm") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( coarse grain method algorithm ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("coarse grain method algorithm") or ("modified multiobjective optimisation algorithm"))*.
