Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
mental algorithm » genetic algorithm, control algorithm, mppt algorithm
modified adam » modified near
using mental » using metal, nursing mental, using medical
modified df » modified _, modified bi1
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 mental algorithm ) or ( ((modified df) OR (modified adam)) optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code using mental algorithm ) OR ( ((modified df) OR (modified adam)) optimisation algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code using mental algorithm ) or ( ((modified df) OR (modified adam)) optimisation algorithm ))*".
