Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, and user input. Here is an example: "We could create a GroverOptimizer object and directly use its solve method with qp."

A block of code is set as follows:

import dimod 
 
J = {(0,1):1, (0,2):1} 
 
h = {} 
 
problem = dimod.BinaryQuadraticModel(h, J, 0.0, dimod.SPIN) 
 
print("The problem we are going to solve is:") 
 
print(problem)

Any command-line input or output is written as follows:

$ python3 script.py

Important ideas are highlighted in boxes like the following:

Important note

I am a box. I feel important. That's because I am important.

We sometimes include material for those of you who want to learn more. We format it as follows:

You don't have to read me if you don't want to.
