## basic solver
```clojure
(let [solver (new-mpsolver "myprogram" "GLOP_LINEAR_PROGRAMMING")
x (.makeNumVar solver 0.0 1.0 "x")
y (.makeNumVar solver 0.0 2.0 "y")
objective (.objective solver)]
(.setMaximization objective)
(.solve solver)
(is (= 1.0 (.solutionValue x)))
(is (= 2.0 (.solutionValue y))))
```
## simple linear problem
```clojure
(let [solver (new-mpsolver "myprogram" "GLOP_LINEAR_PROGRAMMING")
x (.makeNumVar solver 0.0 infinity "x")
y (.makeNumVar solver 0.0 infinity "y")
objective (.objective solver)]
(doto objective
(.setCoefficient x 3)
(.setCoefficient y 4)
(.setMaximization))
(doto
(.makeConstraint solver -infinity 14.0) ; x + 2y <= 14
(.setCoefficient x 1)
(.setCoefficient y 2))
(doto
(.makeConstraint solver 0.0 infinity) ; 3x - y >= 0
(.setCoefficient x 3)
(.setCoefficient y -1))
(doto
(.makeConstraint solver -infinity 2.0) ; x - y <= 2
(.setCoefficient x 1)
(.setCoefficient y -1))
(.solve solver)
(is (=== (.solutionValue x) 6))
(is (=== (.solutionValue y) 4))
(is (=== (.value (.objective solver)) 34)))
```
