This paper considers the optim, fminsearch and nmplot solvers included in the library functions of the Scilab mathematical software from the point of view of the speed and complexity of their application in solving optimization problems using examples of Rosenbrock functions of various orders. An example of using the described solvers for calculating electrical circuits is given; the optimal value of the local minimum of the falling voltage along a long line as a function of one variable is found. Conclusions are made about the effectiveness of using different solvers of the Scilab mathematical software for circuit calculations.
