The phrase "a second set of solutions" is correct and usable in written English.
You can use it when referring to an additional group of answers or methods to solve a problem, often in contexts like mathematics, engineering, or problem-solving discussions.
Example: "After analyzing the initial results, we discovered a second set of solutions that could also address the issue effectively."
Alternatives: "an alternative set of solutions" or "a different group of solutions".
Quality control (QC) was maintained using a second set of source calibration solutions prepared identically to the calibration standards.
THE CONTROL METHOD The second set of solutions involves taking control of insolvent banks, either by nationalizing them or declaring them bankrupt.
An initial set of three simulations was performed with a 0.2 M NaCl solution and a second set of three equivalent simulations used minimum sodium ions to electrically neutralise the system.
In parallel, a second set of samples was incubated with 10% of a solution of sulfanilamide (5% in 1 N HCl) for 1 min to scavenge nitrite and measure only the remaining GSNO.
Add a second set of lines.
For control, in a first set of experiments specimens were fixed in a conventional solution containing GA.
The long-term solution for the congestion problems is the expansion of the canal through a third set of locks.
In the second set of experiments, HAuCl4 solution was injected from inlet A and TTF solution from inlet B at flow rates of 30 and 370 μL/min, respectively.
These results differ markedly from our previous findings on the OsII iminopyridine complex [Os η- p-cym)(Impy-OH I]PF6, Impy-OH I]PF6rystal structure showhose racemic mixture of enantiomers, (SOs)-[Os(η- p-cym)(Impy-OH)I]PF6 and (ROs)-[Os(η- p-cym)(Impy-OH)I]PF6. 14 Chiral resolution of the second set of enantiomers in solution was hampered by their low solubility.
However, the performance of this heuristic on this instance for a single heuristic execution is not sufficient to assert that the first set of parameter settings will always produce superior results than the second set of parameters, for all initial solutions.
