Si maintenant vous me donnez une équation que vous aurez choisie à votre gré, et que vous desirez connaître si elle est ou non soluble par radicaux, je n’aurai rien à y faire que de vous indiquer le moyen de répondre à votre question, sans vouloir charger ni moi ni personne de la faire. En un mot les calculs sont impracticables.
Évariste Galois
For every polynomial-time algorithm you have, there is an exponential algorithm that I would rather run.

Algorithms are for people who don't know how to buy RAM.
