Initialize an adjacency matrix to represent our graph. An example: ML estimation vs. EM algorithm qM-step: – maximize the E-step – We set the derivative to zero and get (use results from math tables: conditional means and variances, “Law of total variance”) qAt the steady state ( ) we get the same value for the estimate as in ML estimation (max{0,y2-1}) qWhat about the convergence? Start with an example graphs: ... which will be constructed in the next step, gives for all edges the information by how much the flow may be increased or reduced. Also, you will find working examples of finding maximum flow in a flow network in C, C++, Java and Python. Consider the following weighted graph. Step 1 - Consider the first element of the list as pivot (i.e., Element at first position in the list). Flow can mean anything, but typically it means data through a computer network. The idea of this note is to understand the concept of the algorithm by solving an optimization problem step by step. Assume that there is a terminal constraint x(t + N) = 0 for predicted state x and u(t + N) = 0 for computed future control u If the optimization problem is feasible at time t, then the coordinate origin is stable. Example of Dijkstra's Algorithm.
