Cellular Automata and the Railway Model, . are fixed-parameter tractable parameterized by .. We use a dynamic programming approach and define a new dominance rule, which we call the weak earliest deadline rule. This rule narrows down the number of relevant scheduling prefixes enough to complete the search via a fixed-parameter tractable number of dynamic programming states.

To investigate the cycle selection problem with a maximum cycle length equal to 3, we provide an arc-based formulation with an exponential number of constraints that can be separated in polynomial time. All inequalities in the formulation are facet-defining for complete digraphs.

We provide experimental results showing that metabolic pathways and networks with thousands of compounds and reactions can be oriented in a few seconds on a personal computer.

Small States, Colonial Rule and Democracyd, we give two different infinite families of forbidden minimal structures for this class of graphs. We conclude the paper by suggesting an interesting future line of work about the persistency-preservation property of valid inequalities and its potential practical applications.

We show that MCVP is NP-hard for general graphs and it remains NP-hard when the graph induced by the strong edges is unit interval or distance hereditary. On the other side, we provide a polynomial algorithm that properly solves MCVP when the graph is a unit interval graph without triangles with two or more weak edges.
