The transformation of a linear program to one in standard form may be accomplished as follows. First, for each variable with a lower bound other than 0, a new variable is introduced representing the difference between the variable and bound. The original variable can then be eliminated by substitution. For example, given the constraint a new variable, , is introduced with Webb26 juli 2024 · Simplex algorithm starts with those variables which form an identity matrix. In the above eg x4 and x3 forms a 2×2 identity matrix. CB : Its the coefficients of the basic variables in the objective function. The objective functions doesn’t contain x4 and x3, so these are 0. XB : The number of resources or we can say the RHS of the constraints.
