In the Lagrange multiplier method, a constrained problem is reformulated as one of finding the stationary points of an unconstrained function, whereas in the penalty method, a problem with differential constraints is reformulated to one without constraints.

In the Lagrange multiplier method, a constrained problem is reformulated as one of finding the stationary points of an unconstrained function, whereas in the penalty method, a problem with differential constraints is reformulated to one without constraints. Correct Answer True

In the Lagrange multiplier method, a constrained problem is reformulated as one of finding the stationary points of the unconstrained functional IL(v,λ)≡Iv(v)+∫ΩcλG(v)dxdy where λ(x,y) is the Lagrange multiplier. In the penalty method, a problem with differential constraints is reformulated to one without constraints.

Read this statement and state which of the following arguments is/are stronger. Statement: The Central Government should abolish the death penalty in India. Conclusions: I. The removal of the death penalty forever will increase the courage of premeditated and heinous offenders to indulge in such crimes again and again. Therefore, instead of removing the death penalty completely, the use of it in selective and special circumstances is stronger. II. The death penalty itself is equivalent to the state taking life in itself, which is considered a heinous crime. Therefore it should be eliminated.
