Center node: "loosening the notions of compliance and sub behaviour in client server systems"
  Abstract: In the context of “session behaviors” for client/server sys tems, we propose a weakening of the compliance and sub-behaviour relations where the bias toward the client (whose “requests” must be satisfied) is pushed further with respect to the usual definit ions, by admitting that “not needed” output actions from the server side can be skipped by the client. Both compliance and sub-behaviour relations resulting from this weakening remain decidable, though the proof of the duals-as-minima property for servers, on which the decidability of the sub-b ehaviour relation relies, requires a tighter analysis of client/server interactions.

Connected through hyperedge HE-1 (induced by source paper "orchestrated session compliance"):
  with members:
    - "mutually testing processes"
    - "a note on two notions of compliance"
    - "from orchestration to choreography through contract automata"

Connected through hyperedge HE-2 (induced by source paper "a note on two notions of compliance"):
  with members:
    - "on the realizability of contracts in dishonest systems"

The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
