Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified multiobjective mppt algorithm" » "modified multiobjective lot algorithm", "modified multiobjective mom algorithm", "modified multiobjective qspr algorithm"

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

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