Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"affective mapping methods algorithm" » "affective making methods algorithm", "affective learning methods algorithm", "affective graining methods algorithm", "effective mapping methods algorithm", "affecting mapping methods algorithm"

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

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