Talvez deva tentar algumas variações de ortografia:
formulation changes » formation changes (Expandir a busca), formulation challenges (Expandir a busca), population changes (Expandir a busca)
code formulation » code formulations (Expandir a busca), model formulation (Expandir a busca), score formulation (Expandir a busca)
changes decrease » changes increase (Expandir a busca), change increase (Expandir a busca), recharge decrease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code code » code cdc (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code formulation changes decrease ) OR ( in python python python programming ))~.
