x = fmincon(fun,x0,A,b,Aeq,beq,lb,ub,nonlcon) subjects the minimization to the nonlinear inequalities c(x) or equalities ceq(x) defined in nonlcon. fmincon optimizes such that c(x) ≤ 0 and ceq(x) = 0. If no bounds exist, set lb = [] and/or ub = []. example x = fminco...
The performance of ARFO is benchmarked against 28 CEC-2013 benchmarks [36], which comprise five unimodal functions (f1–f5), 15 multimodal functions (f6–f20), and eight composition functions (f21–f28), totalling 28 diverse and difficult minimization problems. The composition functions were sp...
, K)41. We use a ‘hat’ to denote parameters which have been estimated through minimization of the χ2 cost function above and for the estimated (co)variance of such parameters. In the WLS method one uses weights \({R}_{ij}={\overline{R}}_{ij}={\delta }_{i,j}/{\overline{C...

The lsqcurvefit uses the sum of square of errors (SSE) minimization, right? I have tried using it using a set of chemical reactions where some species concentrations are in the 1E+01 magnitude and some are in 1E-02. What I have found is that the local mi...
One example of a design conflict in automotive electronic power steering systems is the conflict between the desire for steering feel stiff and the minimization of road noise. If stiff steering is achieved the system transmits more undesired road noise. To minimize road noise, the steering must ...
and bxμ=−μ∑i=1mln−gix Suppose we choose the usual logarithmic barrier function. The constrained minimizing problem can be approximately reformulated as the following unconstrained minimization problem: minimize P(x,μ)≡ f(x)−μ∑i ln gi(x), where μ denotes a positive parameter. ...
[14] formulized an unconstrained minimization problem for function generation, where the objective function was the sum of the squares of the errors at the selected design points on the two-dimensional input domain. The solution was found by an iterative numerical algorithm. Rao [15] combined a...
