Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"towler learning method algorithm" » "towler learning mom algorithm", "towler learning methods algorithm", "towler graining methods algorithm", "towler learning emotion algorithm", "tower learning method algorithm", "bowler learning method algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("towler learning method algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("towler learning method algorithm") OR ("modified multiobjective optimization algorithm"))*.
• Removing quotes may allow a broader search: (( towler learning method algorithm ) or ( modified multiobjective optimization algorithm ))*.
