PDE Constrained Optimization

Instead of optimization in a finite dimensional setting, or controlling the trajectory of the state as in optimal control, one can consider optimization of systems governed by partial differential equations (PDEs). 298 more words

Laws of geometric figuresThe square:

laws of geometric figuresSquare:- square circumference = side x 4- side of the square = circumference ÷ 4- square area = side x sideAppointed:- Perimeter of the rhombus = side x 4Diamond rib = circumference ÷ 4Rhombus Area = (Large Diameter x Small Diameter) ÷ 2 – Large Diameter = (Area x 2) ÷ Small Diameter – Small Diameter = (Area x 2) ÷ Large Rectangular Diameter:- circumference of the rectangle = (length + width) x 2- length of the rectangle = (circumference ÷ 2) – width- width of the rectangle = (circumference ÷ 2) – length- Area of ​​the rectangle = length x 2- length of the rectangle = area ÷ width- width of the rectangle = area ÷ lengthparallelogram:- parallelogram circumference = (base + leg) x 2 – parallelogram base = (circumference ÷ 2) – leg – parallelogram leg = (circumference ÷ 2) – base – parallelogram area = base x height – parallelogram base = area ÷ height – parallelogram height = area ÷ basetrapezoid:- trapezoidal area = [(large base + small base 9 ÷ 2] x height – trapezoidal height = (area x 2) …. 704 more words
