text: The specific problem is early on in the game, you have an underdetermined system of equations in that you have fewer equations than you have unknowns.\n\nThis situation typically results in numerous possible solutions, but there exist some thechniques, notably Jayne's Formalism, that use entropy maximization techniques to find a "good" solution even though a unique solution cannot be found.\n\nIt is the branch of mathematics known as decision making in the presence of uncertainty.
