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