Talvez deva tentar algumas variações de ortografia:
python sampling » method sampling (Expandir a busca), thin sampling (Expandir a busca), methods sampling (Expandir a busca)
decrease based » decreased base (Expandir a busca), decrease blood (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (Expandir a busca)
sampling time » sampling in (Expandir a busca), sampling bias (Expandir a busca)
time python » the python (Expandir a busca), simple python (Expandir a busca), lines python (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code decrease based program ) OR ( python sampling time python programming ))~.
