We have designed a new logic programming language called LM (Linear Meld) for
programming graph-based algorithms in a declarative fashion. Our language is
based on linear logic, an expressive logical system where logical facts can be
consumed. Because LM integrates both classical and linear logic, LM tends to be
more expressive than other logic programming languages. LM programs are
naturally concurrent because facts are partitioned by nodes of a graph data
structure. Computation is performed at the node level while communication
happens between connected nodes. In this paper, we present the syntax and
operational semantics of our language and illustrate its use through a number
of examples.Comment: ICLP 2014, TPLP 201
