    SIGMIX (Software) Responsible for SIGMIX- a software development project aim at road traffic signal optimization. -Optimization of traffic signal setting: The problem nature is to optimize non-convex problem (but with polyhedral feasible region). -Modelling the dynamics of road traffic: Tracks the bulk behaviour of the evolving states (flow, density). It is done via the theory of finite differencing (FD). -Sigmix-2-Sumo: Converting topology of macroscopic SIGMIX file to microscopic Sumo (Simulation of Urban MObility) xml file. -mixMIX : Calculation procedures discretizing partial differential equations (PDE) of multi-mode (passenger cars and scooters) traffic (multi-phase flow in fluid mechanics analogy) Skills: -Cell Transmission Model (CTM) -Macroscopic Node Model -Genetic Algorithm (G.A.) -Hill Climbing
