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