template<typename IndexType>
void FormatPolynomialKey(std::vector<IndexType> *key, const Vartype &vartype)

Format the input key: for example, {2,1,1}–>{1,2} for BINARY variable and {2,1,1}–>{2} for SPIN variable.

Template Parameters:

IndexType – Used to represent the indices of variables

Parameters:

• key – This may be formatted.

• vartype – The model’s type. cimod::Vartype::SPIN or cimod::Vartype::BINARY.

cimod::Vartype ToCimodVartype(const std::string &vartype_str)

Convert vartype from string to cimod::Vartype.

Parameters:

vartype_str – “SPIN” or “BINARY”

Returns:

cimod::Vartype::SPIN or cimod::Vartype::BINARY

template<typename IntegerType>
void CheckVariables(const std::vector<IntegerType> &configurations, const Vartype &vartype)

Convert vartype from string to cimod::Vartype.

Template Parameters:

IntegerType – The type of spin/binary configuration

Parameters:

• configurations – The spin/binary configuration

• vartype – The model’s type. cimod::Vartype::SPIN or cimod::Vartype::BINARY.

void CheckVartypeNotNONE(const Vartype &vartype)

Check if the input vartype is not Vartype::NONE.

Parameters:

vartype – The model’s type. cimod::Vartype::SPIN or cimod::Vartype::BINARY.
