Abstract
We study systems of linear Diophantine
equations that arise when performing AC-unification of higher-order
patterns by the algorithm recently proposed by A. Boudet and
E. Contejean. Their solution space
presents symmetries which can be exploited to solve them more efficiently.
Keywords: Linear Diophantine Systems.
