(import std.clpr)
Domains
| Symbol | Description |
|---|---|
(clp:real var lo hi) | Closed interval [lo, hi]. |
(clp:real-open var lo hi) | Open interval (lo, hi). |
(clp:real-half-open var lo hi lo-open? hi-open?) | Mixed open/closed bounds. |
(clp:domain-r? d) | True when d is a real-interval domain. |
(clp:domain-r-lo d) | Lower bound. |
(clp:domain-r-hi d) | Upper bound. |
(clp:domain-r-lo-open? d) | Lower bound open? |
(clp:domain-r-hi-open? d) | Upper bound open? |
(clp:domain-r var) | Current real domain of var. |
(clp:r-bounds var) | (lo . hi) of current bounds. |
(clp:r-feasible? store) | True when constraints remain consistent. |
Linear constraints
| Symbol | Description |
|---|---|
(clp:r+ x y z) | z = x + y. |
(clp:r- x y z) | z = x - y. |
(clp:r*scalar k x z) | z = k * x. |
(clp:r= a b) | Equality. |
(clp:r<= a b) | a <= b. |
(clp:r< a b) | a < b. |
(clp:r>= a b) | a >= b. |
(clp:r> a b) | a > b. |
Optimisation
| Symbol | Description |
|---|---|
(clp:r-minimize objective vars) | Linear minimisation. |
(clp:r-maximize objective vars) | Linear maximisation. |
(clp:rq-minimize quadratic linear vars) | Quadratic minimisation. |
(clp:rq-maximize quadratic linear vars) | Quadratic maximisation. |
