I can find the shadow price by solving the DUAL problem with solver.Solve(modelDUAL), but still I would like to find bounds etc. :O)

Hey Thomas,
Not sure if this helps or not, but try this:
```javascript
var solver = require("./src/solver"),
results,
model = {
"optimize": "capacity",
"opType": "max",
"constraints": {
"plane": {"max": 44},
"person": {"max": 512},
"cost": {"max": 300000}
},
"variables": {
"brit": {
"capacity": 20000,
"plane": 1,
"person": 8,
"cost": 5000
},
"yank": {
"capacity": 30000,
"plane": 1,
"person": 16,
"cost": 9000
}
},
};
results = solver.Solve(model,0.0000001, true);
console.log(results);
```

Hi JWally thank you so much for your quick reply :O)
solver.Solve(model,0.0000001, true); tableu contains shadowprices and reduced costs :O)
Allowable decrease and increase for the current solution for the constraints and objective coefficients are not in the console, maybe Excel Solver is slow since it has to calculate these bounds.
Do you know where I can find more info regarding the arguments for solver.Solve(model,0.0000001, true)?

Hi guys... I'm studying the possibility of using this library on a new project and the allowable decrease and increase for the current solution is something very important.
Is there a way to do this with this library?
