# SlsqpOptimizationResult
<Class id="qiskit.optimization.algorithms.SlsqpOptimizationResult" isDedicatedPage={true} github="https://github.com/qiskit-community/qiskit-aqua/tree/stable/0.9/qiskit/optimization/algorithms/slsqp_optimizer.py" signature="SlsqpOptimizationResult(x, fval, variables, status, fx=None, its=None, imode=None, smode=None)" modifiers="class">
Bases: `qiskit.optimization.algorithms.optimization_algorithm.OptimizationResult`
SLSQP optimization result, defines additional properties that may be returned by the optimizer.
Constructs a result object with properties specific to SLSQP.
**Parameters**
* **x** (`Union`\[`List`\[`float`], `ndarray`]) The solution of the problem
* **fval** (`float`) The value of the objective function of the solution
* **variables** (`List`\[`Variable`]) A list of variables defined in the problem
* **fx** (`Optional`\[`ndarray`]) The value of the objective function being optimized, may be different from `fval`
* **its** (`Optional`\[`int`]) The number of iterations.
* **imode** (`Optional`\[`int`]) The exit mode from the optimizer (see the documentation of `scipy.optimize.fmin_slsqp`).
* **smode** (`Optional`\[`str`]) Message describing the exit mode from the optimizer.
* **status** (`OptimizationResultStatus`) the termination status of the optimization algorithm.
