Physics concept taught by Shreesh
S Sahai assisted a student from the University of California, Los Angeles, with a transshipment problem. The lesson focused on setting up the problem in Excel and using the solver function to minimize transportation costs. They defined variables, constraints, and the objective function, and also discussed why the solver naturally produces integer solutions. The learner will work on question three in a future lesson.

Excel Solver
Objective Function
Constraints
Nodes (Network Flow)
S Sahai guided Harshita through a practical application of business analytics, specifically tackling a transportation problem. The lesson centered on structuring the problem within Excel and employing Solver to optimize and minimize transportation costs. Together, they established definitions for inflow, outflow, balance, and constraints, and calculated total costs using SUMPRODUCT. Harshita will finalize the problem setup and solution, which S Sahai will review in their subsequent lesson.
Excel Solver Objective Function
Network Flow Constraints
SUMPRODUCT Function
Inflow & Outflow
S Sahai tutored a student from Brentwood on using Excel's solver function to determine coefficients for linear and quadratic regression models. The learner worked on minimizing the sum of squared differences to find optimal values for B0 and B1 in both linear and quadratic equations. They plan to cover the next question, which involves constraints, in their next lesson on Tuesday.
