Perhaps you should try some spelling variations:
"primary data bayesian optimization algorithm" » "primary data based optimization algorithm" (Expand Search)
"binary ppk codon optimization algorithm" » "binary ppk dog optimization algorithm" (Expand Search), "binary ppk motor optimization algorithm" (Expand Search), "binary ppk igdt optimization algorithm" (Expand Search), "binary pdm codon optimization algorithm" (Expand Search)

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: (("primary data bayesian optimization algorithm") OR ("binary ppk codon optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary data bayesian optimization algorithm\") OR (\"binary ppk codon optimization algorithm\"))".
• Removing quotes may allow a broader search: (( primary data bayesian optimization algorithm ) OR ( binary ppk codon optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("primary data bayesian optimization algorithm") OR ("binary ppk codon optimization algorithm"))*.
