二元二次模型的C++库
jij-cimod的Python项目详细描述
< H1> CIMOD：二元二次模型的C++头集库
C++ +EH3>
如何使用
您应该只在项目中包含一个标题src/binary_quadratic_model.hpp。在
示例
C++ +EH3>#include"src/binary_quadratic_model.hpp"usingnamespacecimod;intmain(){// Set linear biases and quadratic biasesLinear<uint32_t,double>linear{{1,1.0},{2,2.0},{3,3.0},{4,4.0}};Quadratic<uint32_t,double>quadratic{{std::make_pair(1,2),12.0},{std::make_pair(1,3),13.0},{std::make_pair(1,4),14.0},{std::make_pair(2,3),23.0},{std::make_pair(2,4),24.0},{std::make_pair(3,4),34.0}};// Set offsetdoubleoffset=0.0;// Set variable typeVartypevartype=Vartype::BINARY;// Create a BinaryQuadraticModel instanceBinaryQuadraticModel<uint32_t,double>bqm(linear,quadratic,offset,vartype);//linear terms -> bqm.get_linear()//quadratic terms -> bqm.get_quadratic()return0;}
