Since the conjugate gradient method is one of the most effective methods for both unconstrained and constrained optimization, it can be applied without or with preconditioning for solving the basic step of the discretized problem. A comparison of several preconditioned conjugate gradient methods is ...

Notice that this constraint means that the solution will not be at the unconstrained solution (1,1), because at that point x(1)+2x(2)=3>1. x0 = [-1,2]; A = [1,2]; b = 1; x = fmincon(fun,x0,A,b) Local minimum found that satisfies the constraints. Optimization completed ...
We con- sidered several scenarios: access to synapse signs and single-neuron connectivity but not strength, requiring task optimization of synapse counts; access to signs, but requiring optimization of single-neuron connectivity and synapse counts; full connectome measurements but optimization of synapse...
When the functions f, G, and F are continuously differentiable, replacing the unconstrained optimization in (6a) by its first-order necessary condition for optimality and specializing Lemma 1 to the case ϵf:=λF(u)=0 leads to the Karush–Kuhn–Tucker (KKT) first-order necessary conditions...
6a). When unphosphorylated Aurora-A was incubated in the presence of the constrained peptides and ATP, they were found to stimulate Aurora-A kinase activity more effectively when compared to the WT unconstrained control peptide, with the effect being qualitatively more pronounced for the L/R ...
Therefore, in unconstrained markets, equilibrium prices are C.A.P.M. prices. In the next example however, we show that the mixed financial-reinsurance markets we studied in Section 4 may allow for limited arbitrage possibilities at equilibrium. As a consequence, there does not necessarily exist ...

As an antonym, we cannot use "unconstrained node", as engineering is unable to produce nodes that are literally without constraints. To mark the other end of the constrainedness spectrum, the term Capable (as in "capable nodes") has recently become popular. Capable Node: A node that is not...
