Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"boiler forecasting method algorithm" » "boiler focusing method algorithm", "boiler forecasting mixed algorithm", "boiler forecasting mom 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 optimization algorithm") OR ("boiler forecasting method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"boiler forecasting method algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( boiler forecasting method algorithm ))*.
