# A name for a numerical phenomena when using numerical methods

I have a nonlinear solver for equation $$g= c_1f(x_1,y_1)+c_2f(x_2,y_2)$$. Note that $$c_1$$ is much bigger than $$c_2$$. So after using Levenberg–Marquardt algorithm, I could only get $$x_1$$, $$y_1$$ and $$c_2f(x_2,y_2)$$ is ignored by the solver. Is there a proper noun for this phenomenon?
