ABS QUBO Solver Trial
The problem size can be 32 to 32k(32,768) bits due the network bandwidth limitation although ABS QUBO solver can accepts instances with up to 128k (131,072) bits.
The word size of each instance matrix element can be 16/32/64 bits.
Arithmetic precision: Arithmetic precision can be 32 bits or 64 bits. It is fixed to 64 bits for QUBO instances with 64-bit word size. Regardless of arithmetic precision, energy value is always computed/stored in 64-bit precision. If arithmetic/energy overflow is detected, ABS QUBO solver terminates with a warning message.
For higher search performance of ABS QUBO solver, 16-bit QUBO instances and 32-bit arithmetic precision are recommended.
RunTime: The maximum running time can be 1 to 100s.
Target Energy: If a non-zero target energy is set, ABS QUBO solver terminates when a solution with target energy or smaller is found.
