The guiding principle of technicolor is "naturalness": basic physical phenomena should not require fine-tuning of the parameters in the Lagrangian that describes them.

Many of these contain parameters or initial conditions which themselves require fine-tuning in much the way that the early density does without inflation.

But the programs have required fine-tuning to address the needs of the 139 Cuban teen-agers, who set sail at various times in the summer of 1994.

The models now on the market carry only monophonic television sound and usually require fine-tuning.

Theories requiring fine-tuning are regarded as problematic in the absence of a known mechanism to explain why the parameters happen to have precisely the needed values.

The stability augmentation system also required much fine-tuning.

There are some type 2 diabetes complications, such as heart disease, retinopathy, and neuropathy, that may require fine-tuning of your exercise program.

It is the first time that it is on the table, so it goes without saying that it will require fine-tuning in future.

I believe that this issue of coordination will require ongoing effort and fine-tuning.

From time to time, your program may require fine-tuning.
