WebThe linear sum assignment problem [1] is also known as minimum weight matching in bipartite graphs. A problem instance is described by a matrix C, where each C [i,j] is the cost of matching vertex i of the first partite set (a ‘worker’) and vertex j of the second set (a ‘job’). Web25 Jul 2016 · In standard form, linear programming problems assume the variables x are non-negative. Since the variables don’t have standard bounds where 0 <= x <= inf, the bounds of the variables must be explicitly set. There are two upper-bound constraints, which can be expressed as. dot (A_ub, x) <= b_ub.

WebFirst, we will generate multiple samples from a Bernoulli random variable using scipy.stats.bernoulli. We will use mu=0.3 to create 3 samples from the Bernoulli distribution. The expectation and variance of the Bernoulli random variable will be computed, and the sample mean/variance will be compared to the true mean/variance.
