The phrase "heuristic principle" is correct and can be used in written English.
This phrase is typically used to refer to a problem-solving approach that relies on an educated guess rather than a precise solution. For example, "The company used a heuristic principle to quickly come up with a cost-effective solution to the problem."
While acknowledging and indeed exulting in the wondrous appointments of nature, Kant cautioned that teleology can be, for human knowledge, only a regulative, or heuristic, principle and not a constitutive one i.e., a guide to the conduct of inquiry rather than to the nature of reality.
Now there is a heuristic principle that many people have used, though it seems to have no simple formulation.
The basic heuristic principle is that the trapped set ( K_{ Omega cap {mathbb {R}}} ) should replace ( p^{-1} ( [ a, b ] ) ) as everything else escapes.
Others (Connelly 2009; D'Oro 2014) have argued that for Collingwood the principle of verification is not a general criterion of meaning but a heuristic principle of empirical investigation, an absolute presupposition of empirical enquiry.
Pnictogen bonding formation may become an heuristic principle for predicting some of the short contacts that are present in the crystal structures of compounds containing fluorinated atoms of Group 15, particularly when polyfluorinated.
The correspondence rule was a heuristic principle meant to make sure that in areas where the influence of Planck's constant could be neglected the numerical values predicted by such a theory should be the same as if they were predicted by classical radiation theory.
Heuristic principles are suggestive rather than demonstrative (Carmichael 1922, 1930).
Another area being investigated is the putative role of heuristic principles in mathematics.
The heuristic principles which govern forms of enquiry, for Collingwood, are presuppositions, not propositions.
These heuristic principles are not understood to show the path to secure knowledge.
The following general heuristic principles apply for making reasonable selections from the emerging readings.
