Hodge Conjecture. The answer to this conjecture determines how much of the topology of the solution set of a system of algebraic equations can be defined in terms of further algebraic equations. The Hodge conjecture is known in certain special cases, e.g., when the solution set has dimension less than four. But in dimension four it is unknown.

Ultimate Guide to Theory of Constraints | Smartsheet

Basically, a constraint is a step or process that is producing less than what's demanded of it, or it is something that limits profit, or in TOC terms, throughput. Rather than viewing them as problems, Goldratt saw constraints (also known as bottlenecks), as the keys to unlocking productivity.

Metallurgist & Mineral Processing Engineer

In most cases problems are not metallurgical in nature but rather operational and mechanical. Problem-solving is a process and in many operations this ability is absent. All too often many changes are made together without a solution resulting, on more confusion. Most plants learn to live or survive their problems, not to solve them.
