Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"machines forecasting method algorithm" » "mapping forecasting method algorithm", "machines focusing method algorithm", "machines forecasting mixed algorithm", "machines forecasting mom algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines forecasting method algorithm") OR ("modified multiobjective estimation algorithms"))~.
• Removing quotes may allow a broader search: (( machines forecasting method algorithm ) or ( modified multiobjective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("machines forecasting method algorithm") or ("modified multiobjective estimation algorithms"))*.
