Inequality constraints on D-Wave (using PyQUBO)
Inequalities cannot be directly converted into a QUBO form. By inequality, I mean something like this:
0⩽ Expression ⩽ N.
We can introduce a slack variable and convert it to an equality problem:
⟹ Expression + s = N
where:
s ∈ Z,
s ∈ [0,N]
Since the…

How to calculate the $r^{\text{th}}$ digit of $\sum ^{j−1}_{p=i}d^p_{\pm k}$ using PyQUBO?
I am going to implement "turn circuit encoding" method of
Coarse-grained lattice protein folding on a quantum annealer(Babej, Ing & Fingerhuth; 2018) using PyQUBO to run on the DWave qbsolv environment.
In this method I have to implement equation…

How to add constraints to a BQM?
BQM is unconstrained by definition.
I need to submit a knapsack problem with two constraints (equality constraints + inequality constraints) to a quantum annealer (DWaveSampler).
How would you set the problem as a BQM to be sampled fully quantum (no…
