A One-Vertex Decomposition Algorithm for Generating Algebraic Expressions of Square Rhomboids
The paper investigates relationship between algebraic expressions and graphs.
We consider a digraph called a square rhomboid that is an example of
non-series-parallel graphs. Our intention is to simplify the expressions of
square rhomboids and eventually find their shortest representations. With that
end in view, we describe the new algorithm for generating square rhomboid
expressions, which improves on our previous algorithms
