which is a legal, linear constraint.
= 0.4*B3 - 0.6*B2
changed, through simple algebraic rules, to a different form:
but this expression is non-linear. This constraint may be
=0.4 - B2/(B2+B3)
CONSTRAINT is:
both ADJUSTABLE cells. The obvious way to express this
B3 to be no more than 40% of (B3 + B4), where B3 and B4 are
make them linear. For example, suppose you wished to constrain
It is often possible to restructure non-linear CONSTRAINTS to
directly or indirectly (through another cell).
2) No ADJUSTABLE may appear in the divisor of an expression,
or by themselves.
1) ADJUSTABLES may not be multiplied by one another
This means that:
constants.
where X, Y, and Z are adjustable cells, and a, b, c, and d are
aX + bY + cZ + ... + d
expressed as:
From an algebraic perspective, a linear function may always be
+ - * / SUM()
operators may be used:
must contain "linear" formulas. This means that only the following
