The limit of as approaches 1 exists and is 1 , as approaches 1 from both the right and left. Therefore .4. is not defined. Note that 1 is not in the domain of as defined by the problem, which is indicated on the graph by an open circle when .5. As goes to 0 from the right...
Another variant of the cutting problem involves the assignment of circles to pre-defined rectangles. We introduce a new global optimization algorithm, based on piecewise linear function approximations, which converges in finitely many iterations to a globally optimal solution. The discussed formulations ...

but it is a piecewise function in parametric form. The dependence of parts of the curve on various control points is defined by a set of "knots" automatically chosen by the algorithm. These knots also determine the range of the curve. A cubic, or order 4, B-spline curve is produced as...
An extended goal programming approach with piecewise penalty functions for uncertain supplier-material selection problem in cardboard box manufacturing sys... In this study a real case multi-objective material and supplier selection problem in cardboard box production industries is studied. This problem ...
This example solves the problem by using a weighted multiclass Dice loss function [4]. Weighting the classes helps counter the influence of larger regions on the Dice score, making it easier for the network to learn how to segment smaller regions. This example shows how to perform brain ...
r_{\theta} is the residual of PINN. (the original doc says that r_{\theta} is the PINN itself, I am confused about it.) Example: Burgers Equation To make the problem concrete, the author stipulates that we are considering a 1D Burgers equation on the spatial domain \mathcal{D} = ...

Unexpected end of file reached in data file. What does this error message mean, and is there a way to address the problem? Thanks, Charu Mathur Linda K. Muthen posted on Wednesday, June 16, 2010 - 2:45 pm It sounds like you are reading your data incorrectly. You may be ...
the coefficients of such linear combinations become the unknowns of a finite-dimensional nonlinear programming problem. We propose to insert ”free” parameters to be optimized in the basis functions, too. This justifies the term “Extended Ritz Method.” If the optimal solutions of functional optim...
