Software-based approximate computing for mathematical functions
… since 1985, but the situation for floating-point mathematical libraries and even some hardware operations such as fused multiply-add is more nuanced as there are varying opinions on which standards should be followed and when it is acceptable to allow some error or when it is necessary to be …

The State-Based Peridynamic Lattice Model
… material is continuous and can be represented by mathematical functions. This is an unreasonable assumption for concrete due in part to the fact that concrete cracks and the continuum mechanics model cannot directly handle fracture. In response to some of the limitations of continuum mechanics, …

Parametric Inversion of Programs
… output. However, this is ambiguous for most functions since the function may have multiple inputs that produce an output. Parametric inversion takes a new approach to solving inverse problems by proposing a method to make a non-injective (many-to-one) function invertible through a parameter. …
