Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
morse algorithm » source algorithm, mom algorithm
modified game » modified male
modified adam » modified df, modified near
using morse » using force
code » core

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code using morse algorithm ) or ( ((modified game) OR (modified adam)) optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code using morse algorithm ) OR ( ((modified game) OR (modified adam)) optimisation algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code using morse algorithm ) or ( ((modified game) OR (modified adam)) optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( code using morse algorithm ) or ( ((modified game) OR (modified adam)) optimisation algorithm ))*.
