Perhaps you should try some spelling variations:
initialization algorithm » optimization algorithms (Expand Search)
service initialization » services utilization (Expand Search)
codon optimization » dog optimization (Expand Search), motor optimization (Expand Search), igdt optimization (Expand Search)
time service » time series (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( binary time service initialization algorithm ) OR ( binary scale codon optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary time service initialization algorithm ) OR ( binary scale codon optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary time service initialization algorithm ) OR ( binary scale codon optimization algorithm ))*.
