Abstract: Inactive constraints do not contribute to the solution of an optimal control problem, but increase the problem size and burden the numerical computations. We present a novel strategy for ...

While math word problems are widely used in classrooms at all grade levels to help put numbers, operations, and equations into context and connect math to the real world, they also increase the ...

THE calculating machine for the solution of differential equations constructed by Dr. V. Bush, of the Massachusetts Institute of Technology, has attracted a great deal of attention, and a similar ...

A math word problem is a narrative with a specific topic that provides clues to the correct equation with numerical quantities and variables therein. In this paper, we focus on the task of generating ...

Word problems are often described as “math stories” and can put complex mathematical operations into a more approachable form for students. But students often struggle when they see a combination of ...

Working memory is like a mental chalkboard we use to store temporary information while executing other tasks. Scientists worked with more than 200 elementary students to test their working memory, ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...
