Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"boiler forecasting method algorithm" » "boiler focusing method algorithm", "boiler forecasting mixed algorithm", "boiler forecasting mom algorithm", "bowler forecasting method algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("boiler forecasting method algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"boiler forecasting method algorithm\") OR (\"modified multiobjective optimizer algorithms\"))*".
• Removing quotes may allow a broader search: (( boiler forecasting method algorithm ) OR ( modified multiobjective optimizer algorithms ))*.
